This article was quickly published in the top journal "Magic". In just four pages, the entire academic city exploded in an instant. People discussed the relationship between electricity and magnetism. Whether the rotational force conforms to magic mechanics has caused widespread controversy.

Thankfully, all is not settled and no one has had their heads blown.

In the morning sun, the city of academics, a city completely composed of wizards, is still busy with countless golems and activated constructs. Occasionally, I see two or three wizards, discussing loudly about "electric current" Topics like Magnetic Effects, Rotational Forces, etc.

In the auditorium where wizards gather and exchange daily, many wizards gather here spontaneously. They discuss eagerly and intensely, their faces flushed, and they don't look like a powerful wizard at all, but more like vendors and customers in a vegetable market.

"Rotational force is also a force, so it may not be classified under magical mechanics."

"That's not necessarily the case. Master Ace also said that magic mechanics is only a relative truth and has its scope of application. Once it exceeds the scope, the truth becomes a fallacy."

"If you directly assume that magic mechanics is wrong, I'm afraid it's also a fallacy."

"Not assuming that magic mechanics is wrong, but recognizing the concept of relative truth, I think you are caught in your own stubbornness."

Discussions broke up unhappy, and many wizards did not focus on the rotational force. They were more interested in the magnetic effect of current. Although the rotational force and the magnetic effect of current are inseparable, it is clear that the concept of electromagnetism is fascinating. Lots of room for imagination.

In Layton's laboratory, as the wizard who invented the "Brue Stack", Layton is very sensitive to academic papers on electricity. After reading Thales' short four-page paper, he was greatly shocked.

"Thales is really a genius. He was able to use such a simple experiment to discover the magnetic effect of current. Thanks to Lord Ace's magic net, otherwise electricity would not be able to develop so fast. I think the rotational force should explain the magnetic phenomenon. The key, magnetism, electricity, gravity, I need new experiments."

He quickly buried himself in the laboratory and kept designing experiments. After dozens of failures, he finally designed a successful experiment.

Place two wires in parallel, one of which is fixed, and the other is suspended. You can choose freely. By changing the magnitude and direction of the current and the length of the line segment, you can measure the change of the position of the wire.

The suspended wire can freely twist and swing, and the swing angle can be calculated with the meter above.

Suspended wires are parallel to fixed wires. When both wires are connected to power, they interact and the dangling wire wiggles.

The results of the experiment are as follows:

When the current direction is the same, the two wires repel each other; when the current direction is opposite, the two wires attract each other.

The force between the wires per unit length is inversely proportional to the square of the distance between them, and proportional to the magnitude of the current.

Layton organized his experiments into a paper, and the power of the great source also rushed into Layton's body through the magic net. His power was enhanced to a certain extent, but this enhancement was only to strengthen his strength at the golden wizard level. The strength is not enough for him to break through the legendary wizard.

But even so, his discovery is still very great, this law once collided with magic mechanics!

Layton breathed a sigh of relief for no reason, and murmured: "The rotational force generated by electricity is definitely suitable for long-distance action. There is no doubt that we have not broken through the rule of magic mechanics."

Both regretful and fortunate, with inexplicable emotions, Layton mailed this paper to the editorial department of "Magic".

Layton's thesis has aroused widespread repercussions, and many fans of magical mechanics are celebrating. This is undoubtedly another victory for magical mechanics, and it is a great embodiment of Ace's crown.

At the same time, Leiden also became famous. He began to be as famous as Thales in the field of electromagnetism, and was called "Electromagnetic Double Blades" by wizards, and the new theory began to be called "Electricity and Magnetism".

Ace quietly observed this electromagnetic revolution set off by the realm of the sky. This is a revolution about force, and it is the result of the natural birth of the wizard civilization that Ace has cultivated for many years. He readily accepts all of this, and this The changes had a more profound impact on the entire wizarding world.

This world is branded more and more with the marks of wizards, and it is more and more in line with its name, the world of wizards.

There are more and more studies on electricity and magnetism. As a wizard who loved electricity very much at the beginning, Allen is also doing research. He has returned to the realm of heaven from the blood-origin planet, while Eva and Luther stayed on the blood-origin planet. , continuing the social experiment.

Blue and Allen hit it off, and the two of them formed the Blue-Ace Joint Laboratory. Their first project was to try to explain magnetic phenomena.

Allen said to Bruce: "I think that magnetic phenomena are essentially electric currents. According to the current research in the microscopic field, we have not found hypothetical atoms, but molecules have been observed. We can assume that all molecules have electric currents, and then Use hypothetical thinking to try to explain electricity and magnetism."

Blue also agreed: "Just like the phlogiston hypothesis back then, we can first approach the truth in an approximate way. As long as we can understand the reality of the world to a certain extent, we can get positive feedback from the world, and even take the opportunity to break through the legend. level."

They began to discuss theoretical hypotheses all day long. Alan had a nap and dreamed that he became very small, as small as a molecule.

Each molecule is shrouded in a circular current, which is chaotic with each other. Allen directed the molecules to line up, adjusted the direction of the current, and suddenly woke up.

He got up one by one, found Bruce who was sleeping and shook him awake and said: "If every molecule, every molecule that makes up an object has a circular current, we assume it is a meta-current, and this meta-current produces magnetism. The elemental current of the object is chaotic, so the generated magnetic forces cancel each other out, and there is no magnetism at the macroscopic level.

When there is a strong magnetic effect outside, the direction of the molecular current of the object is the same, and the direction of the magnetic field is also constant, and the object is magnetized from a macro perspective. "

When Bruce heard this, he felt that this statement was interesting. The two discussed it all night, and finally wrote a paper called "Molecular Elemental Current Hypothesis", which was published in "Spell Wisdom".

Because of the lessons learned from the phlogiston hypothesis, they emphasized at the beginning that this is just a hypothesis. Even so, this hypothesis still explains many things to a certain extent. According to this hypothesis, Allen also successfully constructed several magnetic spells.

Many wizards who don't pay attention to theory see the powerful power of magnetic spells, so they use them directly.

But Allen was still dissatisfied. He tried to explain the meta-current from the perspective of gravitation and action at a distance, but failed. Unwilling, he needed experiments to provide evidence, so he and Blue designed such an experiment.

Fix the coil and hang a light copper ring. When the coil has a current passing through it, a strong magnetic field will be generated.

Allen thought that if a strong magnetic field can magnetize the copper ring, that is, the molecular currents take the same direction, then the copper ring will shake when it is close to a small magnet.

Unfortunately, things backfired, and when Blue brought the bar magnet closer, the copper ring did not change.

Allen frowned and said, "Maybe copper is not as easily magnetized as iron."

Blue nodded. "Let's redesign the experiment and replace the magnetic strip with a stronger horseshoe magnet."

This time the experiment was very weird. The moment the power was turned on and off, the copper ring twisted slightly, and soon returned to its original shape. When the current continued, the copper ring was the same as last time.

Both Blue and Allen noticed the momentary moment when the power was turned on and off, and Blue said: "Maybe there are some substances that cannot be magnetized very easily like iron, and may only be magnetized briefly."

Allen believes: "Magnetic induction can generate electric current, but this has nothing to do with the molecular elemental current hypothesis we want to test."

When he spoke, he also forgot that this was just a hypothesis, which may have nothing to do with the actual situation. The two of them organized this experiment into a paper, and lightly mentioned the phenomenon of induced current.

Can magnetism generate electricity?

Such an answer that might change the world was handed over by Allen and Blue, and Thales, who saw the paper, widened his eyes, and he was keenly aware that the answer to magnetism and electricity might be hidden in it.

However, after repeating Allen's experiment, Thales found nothing, not even the small rotation they mentioned.

Thales, who was very puzzled, came to ask Alan and Bruce for advice. After some conversation, he learned that Bruce had written the experiment report wrong, and the copper ring was written as a copper plate.

Thales said goodbye and thanked the two, and then continued the experiment. After many failures, Thales redesigned the experiment.

His new experiment is very simple. A coil is wound on both sides of an iron ring, one side is connected to the power supply, and the other side is connected to a small magnetic needle to monitor the current.

When the switch is turned on or off, the magnetic needle deflects and returns to its original position after oscillating.

"It's not wrong, this is magnetism-generated electricity! It's just that the induced current is too short, and many people have not observed it. I am lucky to stand on the shoulders of giants again."

Thales was not in a hurry to publish a paper, but continued to conduct a large number of electromagnetic experiments, and finally confirmed that the induced current can be divided into five categories: changing current, changing magnetic force, constant current in motion, moving magnetism and A conductor in motion in a magnet.

He synthesized all the experimental results and named these five phenomena "electromagnetic induction".

The magic net has mobilized the source force to vibrate, and it seems that as soon as Thales completes the thesis, the world feedback will come under the guidance of the dream core.

Since the birth of the magic net, the world's feedback has no longer caused violent natural phenomena. Transmission through the magic net can save energy to the greatest extent and reduce the movement during feedback.

Thales didn't notice this change, he murmured: "How to explain the electromagnetic induction, how to explain it?"

Thales left the half-written thesis there, and Thales returned to the laboratory. The closed-loop coil current of the "Bleu stack" is still flowing, and it seems to have some kind of inertia, so it always wants to keep the original state. Some look.

When the magnetic field in the coil changes, the coil will be in a state similar to tension, and an induced current will be generated. The induced current will generate new magnetism in the coil, and the new magnetism will prevent the change of the external magnetism, and always want the coil to be in a balanced state.

Thales murmured, "Perhaps we can call this state of equilibrium an electrotonic state."

But this state was too vague. Thales accidentally put iron filings on a piece of white paper, and the white paper was placed on top of the magnet, and found that the iron filings were distributed regularly.

He said in surprise: "This kind of distribution seems to have an invisible line, which can be called a magnetic force line. The explanation of electric tension is not as simple and clear as this magnetic force line."

So a tome paper called "Electromagnetic Induction and Magnetic Field Lines" was born. When Thales wrote the last word, the new source force merged with the original source force that was waiting here through the magic net, and the world's feedback continued. Instantly entered Thales' body and soul.

Cleansing and improving his life essence, allowing him to be promoted to a second-level life in an instant, this promotion is so smooth that Thales feels a little unreal.

"This kind of feedback should be an important discovery, right? It's really unexpected that the promotion went so smoothly."

The soul storage space has naturally evolved into a world of mental images, and a phantom of a magical model in the shape of a magnetic force line has also been suspended in the world of Thales' mental images.

He was not in a hurry to establish a basic spell model for his mental world, but mailed this paper through the shadow crow, lying on the bed and sleeping soundly.

The next day, the editorial department of "Magic" added a special issue almost overnight, selling Thales' tome as a special issue alone.

People rushed to buy, read the latest research results of Thales, a large number of detailed experimental evidence, five clear phenomena, and the concept of magnetic lines of force, which convinced all the wizards who read it, and Bruce and Allen were even more convinced. They looked at each other and smiled wryly.

Blue said: "Thales is indeed a genius. He thanked both of us in particular, and modestly said that the result was discovered with us, but we both knew it and we ignored it."

Allen nodded: "Indeed, although we have given Thales some inspiration, the five phenomena and the concept of magnetic force lines he summed up are definitely genius and original."

The two wrote to the Academic Committee of the High Tower again, refusing the honor that Thales wanted to share with them. Thales, who had just woke up from his sleep, heard about this incident. Finally, the last three shared the honor.

On this day, Ace summoned all the legendary wizards and held a meeting of the Supreme Council.

A newcomer came to the jury, Big Hat Logan, who finally obtained enough source power to break away from the planet he dominated and ascend to the realm of the sky.

So far, there are seven legendary wizards in the wizarding world, Bayern, Dana, Betty, Werther, Warren, Laval, and Logan, and the Supreme Council of the Magic Council also has eight members including Ace.

After everyone arrived, Ace said: "We have gathered everyone today. There is only one proposal. I propose to set up a number of outstanding academic awards to encourage and honor our wizards to devote themselves to magic research with a more focused spirit."

Rotating chairperson Dana stood up and bowed slightly, and asked gently: "Master Ace wants to set up a series of awards for academic research achievements?"

Ace nodded and said: "This is how I plan to set up the magic award, the highest comprehensive award, and the element award, the astrology award, the life award, the soul award, the alchemy award and the contract award. There are seven awards in total. It is not awarded every year, as long as a wizard's academic achievement has been evaluated by the Academic Committee for its great history, great pioneering and great originality, we will award the award.

If no one meets, we cannot lower the bar and the award will be postponed. "

All the legendary wizards nodded, and Bayern asked: "Then how do we set up the awards?"

Ace said: "My preliminary plan is to reward a top-grade gold-level magic item and a large number of magic stones for the highest award in the discipline. The overall highest award is a top-level legendary-level magic item and two top-quality gold-level magic items. The specific standards and operations The details are for you to discuss and decide."

After finishing speaking, Ace disappeared in a flash and disappeared into the conference room. The legendary wizards looked at each other, and the rotating chairman Dana stood up and began to host the discussion.

In the new world, there is no wizard's original agreement, but Ace, as the master of the world, still continues the agreement, so he also knows a series of spell models obtained from electromagnetic research.

These spell models in turn adjust his mental image world and the projected demiplane "dream world".

The entire dream nebula kept flickering, and Ace murmured with white eyes shining: "It's really not easy for me to wait. If it wasn't for cultivating the endogenous force of wizard civilization, I really wanted to speed up all of this on my behalf."

A cloud of star dust gathered in front of him, and a picture appeared, which was Thales.

Thales looked excited. He had just confirmed through experiments that the induced current is directly proportional to the conductivity of the conductor and inversely proportional to the resistance.

"That's right, the current and the induced current produced by the Brue pile are the same thing. Since they have the same nature, the induced current should also have an electromotive force, which is the so-called induced electromotive force, and the induced current is produced by the induced electromotive force.

The relationship between the two is the same as the relationship between electromotive force and current, the induced electromotive force is the cause, and the induced current is the effect. "

While talking, Thales wrote vigorously, "There may not be induced current in the changing magnetic force, but there must be induced electromotive force, just like water flowing down a mountain, no matter whether there is water or not, the mountain must exist.

If there is a closed loop, the induced electromotive force will have 'water'. When the magnetic force in a loop is enhanced, the direction of the induced magnetic force generated by the induced current in the loop is opposite to the direction of the external magnetic force, just like refusing the external magnetic force to enter the loop; when the external magnetic force Weaken, the direction of the induced magnetic force is the same as the external direction, as if to keep the external magnetic force there, this change is the same as the inertia.

Here I propose a concept called "magnetic flux", which is simply understood as the strength of magnetic force lines passing through a unit area, where the strength refers to the number and density of magnetic force lines.

In this way we can explain the conditions under which the induced current arises: the magnetic flux passing through the closed loop changes.

This can also explain Allen-Brue's copper ring experiment, because the magnetic flux in the copper ring changes, the induced current is produced. "

After finishing all this, Thales put down the paper, and said with bright eyes: "Actually, I used a copper plate, and there should be an induced current, but the moment of inertia of the copper plate is too large, so it is not easy to rotate. If this is the case, it should be possible. Make a real generator based on the principle of induced current!"

He made a base, then made several wooden brackets, fixed a U-shaped magnet flat on the bracket, then placed a copper plate in the middle of the U-shaped magnet, and reinforced the shaft and handle, plus the corresponding of wires.

Shake the handle, and the copper disk will rotate. From the edge of the copper disk to the center of the circle, it is equivalent to a conductor. When the conductor moves in the magnetic force line, it will cut the magnetic force line, thereby generating an induced current. Such a hand-operated copper disk is the first generator!

Although the current produced is very weak, far inferior to magic power generation, it is still of great significance, because all the principles are the same.

The spell model in Thales' mental world is becoming clearer, and with the clarity of thinking, the "generator" spell in the purely magical sense is gradually born. The principle of electromagnetic rotation will be the cornerstone of the application of electromagnetic magic.

Layton, who was sleeping, heard the sound of the shadow crow knocking on the window, rubbed his eyes and got up, muttering in a low voice: "Why is it here again, and another explosive new discovery?"

He took out a scroll from the mouth of the shadow crow, and stuffed it skillfully with a few magic stones. Layton opened it, and suddenly his sleepiness dissipated. Thales, who proposed the concept of magnetic force lines, made a new discovery. Machine, and the principle he is based on is even more dazzling.

"The principle of electromagnetic rotation, induced electromotive force, and magnetic flux are simply the wisdom of the apocalypse. If Lord Ace laid the foundation of mechanics, then Thales is the cornerstone of electromagnetism."

At the same time, the highest jury also issued the No. 1 order of this year, in the name of Ace, to establish the highest academic award, the Ace Magic Award, and to set up classification awards such as the Bayern Astrology Award, the Logan Element Award, the Warren Life Award, and the Werther Award. Soul Award, Betty Alchemy Award and Dana Contract Award, a total of seven awards.

Among them, Varen and Dana were not wizards specializing in life magic and contract summoning magic, but these two disciplines required two legendary wizards to be named, so they had no choice but to name them and officially take charge.

In fact, if we only talk about life magic, Lich Werther is very proficient in it. Warren, who drove the ducks to the shelves, began to visit Werther often, asking him for the mysteries of life magic.

After the establishment of the academic award, Thales was notified almost immediately and became the first winner of the Bayern Astrology Award, while Blue, Allen and Leighton were also ranked in the following years. Thales's Contributions are not only eligible for the Bayern Astrology Award, even the Ace Magic Award is also eligible.

However, considering the weight of the awards, the highest jury thinks that it is more appropriate to award the subject awards first, and then the highest award. Therefore, a tradition has also been formed. To win the Ace Magic Award, one must win the highest award in the six major subject categories.

Bayern also found Thales in person. Having the title is not only an honor, but also a responsibility. As the named legendary wizard, Bayern must personally make two golden magic items for Thales.
