It took Anthony a long time to come back to his senses, and he murmured softly, and then suddenly remembered that the mutual repulsion and attraction between positive and negative charges were very similar to the properties of magnets.
"So electricity is magnetism, and magnetism is electricity?" Anthony said excitedly, as if he had discovered a new continent.
He felt that he had glimpsed the mysteries of thunder and magnetic fields.
"You could say that electricity and magnetism are two inseparable, interdependent aspects, just like water and ice..." Lin En nodded.
Anthony seemed excited, but then he became confused. Since the two things have the same origin, why do they appear in two different forms?
Many questions kept flashing through his mind, and Anthony could only look at Lynn anxiously, waiting for his answer.
"If you want to know this, you must first understand what a magnetic field is!" Lin En explained with a smile. "According to the research of scholars from the [Secret Law Society], it is a special form of matter that exists in the space around magnets, electric currents, and moving electric charges. It is a vector field that has a direction and value at any position in space..."
"For example, the planet under our feet is a huge magnetic field!" Lynn stretched out his right hand and snapped his fingers, and a huge blue planet appeared in front of Anthony.
Due to limited knowledge of the entire continent, most areas are covered by thick clouds.
But this is obviously not the point. After Lin En finished speaking, countless materialized magnetic lines extended from the North and South Poles, drawing graceful arcs, like a big net wrapping the entire planet in the center.
Anthony stared at the huge planet beneath his feet, shocked beyond words. At this moment, he no longer cared to figure out why the continent was a sphere, and asked in astonishment.
"So the continent beneath our feet is a huge magnet? That's why everything is attracted to the surface?"
Anthony immediately remembered the theory of charged elements that Abel had mentioned to him. Doesn't this explain the phenomenon of "things falling towards the earth"?
"No, that's actually the effect of the planet's gravity." Lin En said with a smile, "But magnetism and gravity are indeed very similar in some ways..."
Using the huge planet as a model, Lynn explained to Anthony the mysteries of electricity and magnetism, from magnetic lines of force and magnetization to electromagnetic induction, and then to the mutual influence and conversion between electric and magnetic fields.
As the basic building block of the universe, the electromagnetic phenomena in the quantum field are so profound that it would take days and nights to talk about them.
Things such as sound, electricity, magnetism, light, color, heat transfer, thermal radiation, chemical reactions, and even the formation of life ultimately come from electromagnetic force!
Even if a person spends his entire life exploring any branch of the field, he may not be able to fully understand it.
This is also the reason why Lin En did not cling to this knowledge and develop related magic on his own. After all, it is a pipe dream for him alone to summarize and organize the crystallization of thousands of years of human wisdom, combine it with magic, and deduce it to a higher level.
Whether it is the development of science or magic, it cannot be accomplished by one person...
Originally, Anthony thought that his understanding of Thunder was deep enough, except for the most critical cause. However, after Lin En's explanation, he realized that his knowledge was so shallow! Electrons, electric charges, alternating current, direct current... and constant magnetic field, alternating magnetic field, pulsating magnetic field...
All these concepts and nouns rushed into his brain, making Anthony feel ashamed of his research over the years.
Although he created many powerful thunder magics, discovered the phenomenon of electricity generating magnetism, and even created alchemical runes that could induce electromagnetism, his understanding of thunder and lightning was undoubtedly superficial.
"Sir Lin, I wonder which master or legendary wizard is the research result of these theories..." Anthony asked curiously.
"The development of electromagnetism is not the result of the efforts of one or two people, but the joint research result of many scholars in the Secret Society..." Lin En began to speak.
"For example, Master Faraday discovered the phenomenon of electromagnetic induction, Master Ampere measured the direction of magnetic flux lines, Master Millikan used the oil drop method to measure the charge of an electron, and so on..."
In order to fit the identity of a wizard, Lin En tampered with the stories of these sages into a different form.
Anthony couldn't help being fascinated just by listening to it, and he wished he could join them and discuss and study the mysteries of the electromagnetic field with these masters.
However, what surprised him was that Lin En did not mention his own contribution, but had such a deep understanding of the development and inside stories of electromagnetism!
This is obviously abnormal. Magic doctrines and theories are so valuable that no one would pass on all their research to another person without reservation, unless it is a master-apprentice inheritance, academic exchange between peers, or for other purposes.
For example, just now Lin En explained to him many electromagnetic theories and phenomena, but he still avoided talking about many key issues and spoke very vaguely...
Of course Anthony could see that these were all hooks, but his thirst for knowledge made him unable to care about so much. Even if there was a poison inside, he wanted to taste the sugar coating first.
Lynn talked for a long time, and after arousing Anthony's emotions, he took out his trump card!
"There are many theories that describe electromagnetism, but generally speaking, they can all be summarized in this set of mathematical equations!"
The moment Lin En finished speaking, extremely bright spots of light lit up in the void. They gradually gathered together, outlining four mathematical equations composed of letters and symbols.
They are Gauss's law describing how electric charges generate electric fields, Gauss's law of magnetism that explains the non-existence of magnetic monopoles, Maxwell-Ampere's law describing how electric current and time-varying electric fields generate magnetic fields, and Faraday's law of induction describing how time-varying magnetic fields generate electric fields.
This formula can be said to be the culmination of everything. It unifies electricity and magnetism in a nearly perfect way, predicts that light is an electromagnetic wave, and lays the foundation of electromagnetism!
