The correct way to open the sprite

"Hahaha, Lord Dick is indeed an excellent warrior. Look at this action, he is so agile."

Feng Yu laughed loudly, and everyone laughed too. Dick blushed and shouted: "Is it my fault? No one here knew how powerful your wooden handle grenade was during the experiment.

Who knows if this thing of yours is like a wooden handle grenade, it goes off with a bang."

Feng Yu smiled and said, "How about I stand closer than you?"

Dick argued: "I think it's the fault of the experimental weapon that fell down anyway. It's all your fault that the thing you tinkered with is too powerful."

"That's called conditioned reflex"

"Yes, that's the reflection."

Although Feng Yu was joking with Dick, he was actually shocked because the arc between the two copper wires was obviously very large, not like a weak arc. The connected copper wire had been faintly red just now.

Feng Yu was very sure that his generator would never be able to create such a large arc on earth.

However, he is just a second-hand man, and he has no problem doing small scientific experiments. If you ask him to tell you the reason, he will turn black. This can only be attributed to the fact that this is a world of high demons.

Clarence interrupted the two people's chat and said eagerly: "Darren, is this the power of thunder and lightning?"

Feng Yu said: "It is electricity, but not thunder and lightning. Thunder and lightning are products of nature, and this kind of electricity was created by us."

Clarence asked everyone's doubts: "I understand that boiling water and steam push the piston, but why can magnets and copper wires produce electricity?"

"To be precise, it is the electricity generated by the interaction between magnetic induction lines and metal."

As he spoke, he picked up a piece of paper, sprinkled some iron powder on it, and then placed magnets on both sides. After gently shaking the paper twice, the iron powder seemed to be stirred by some force and turned into a belt. Regular patterns.

"You see, magnets attract steel by relying on this invisible magnetic force. We call this invisible force magnetic induction lines.

In other words, this force is like countless threads. Although it cannot be seen or touched, we can still prove its existence through this small experiment.

When metal passes through a place with dense magnetic induction lines, electricity will be generated in the metal.

The reason why I wrapped so much copper wire together was to get more electricity. "

Dick said on the side: "Then what is the use of this kind of electricity? It can smelt metal like you said."

“Not only that, electricity is an energy source that is more widely used than steam engines and is more powerful than steam engines.

After all, the steam engine is just the use of water vapor, while television is the embodiment of thunder.

Therefore, the power of electricity is greater and its application range is wider. It can not only smelt metals, but also drive machinery, making the machinery more powerful and stable. "

As Feng Yu spoke, he moved out something similar to a generator and placed it opposite the generator.

He connected the copper wire and said to Dick: "If you still can't shake it, I can change it."

Dick was afraid that someone would come up and snatch it from him, so he walked to the crank in two steps and started shaking it again.

As the generator speed increases, the motor rotor over there also slowly rotates.

Everyone exclaimed: "It's moving, look quickly"

Feng Yu: ""

"You see, rotation generates electricity, and the electricity can make the machine rotate again. This is what electricity does."

Feng Yu said, unscrewing the connecting wires, connecting them to a short section of very thin spiral metal wire, and placed some scraps of paper inside the metal spiral.

He glanced at Dick, who immediately shook the handle of the generator vigorously again.

Feng Yu asked Clarence to make the metal wire. It used iron with a lot of impurities and its resistance was much higher than that of copper wire. As a trace of smoke arose, the paper burned on its own without any external force.

Feng Yu said to the surprised people: "This is the heat generated by electricity. Because the current is very small, it can only ignite paper scraps. As long as there is more electricity, then it can ignite without the need for a flame. Melts a lot of metal.

Electricity generates heat to melt metal, which is a more efficient way to melt metal than burning flint and is also a way to smelt stronger metals. "

Before Feng Yu finished speaking, the paper scraps had already burned out, and everyone saw the red spiral metal wire.

Feng Yu signaled Dick to stop. After Dick let go, he said, "Oh, Earth, you can really control the power of thunder and lightning. This is really amazing."

Clarence said: "This is incredible, how did you come up with this?"

"I don't know either, just like you don't know why elves can think of using magical elements."

Dick asked: "What if you want to use electricity to smelt metal?"

Feng Yu said: "Just use larger magnets and wrap more copper coils to make the generator rotate faster and emit stronger electricity. But we can slowly experiment with it later."

Nidia asked on the side: "Can electricity be used as a weapon?"

Feng Yu nodded and said: "Of course, direct contact with electricity alone will cause huge damage to living bodies. Electric energy can also drive many powerful weapons, but that requires more advanced knowledge of electricity."

Seeing that Dick, Clarence and others still wanted to ask, Feng Yu quickly waved his hand, but if he asked again, the secret would be revealed.

He said: "Every kind of power in the world is organized into a system, and it would take too much effort to just talk about it.

Tomorrow I will formally establish the Electric Power Research Institute at the institute to teach and study the production and application of electric energy, as well as the characteristics and laws of electric energy.If any of you are interested, you can come and listen to the class. "

Everyone reluctantly left the magical machine that brought thunder, and the students at the institute also returned to their respective rooms. Only Clarence stayed at the end and stopped Feng Yu.

"Darren, come and sit at my place, I want to talk to you."

Feng Yu followed Clarence to his office.

"Darren, your hometown is not on this plane, right?"

Feng Yu was stunned and said: "Why do you say that?"

"Because of your knowledge, I have been learning them and understanding them. Those powerful weapons, magical steam engines, and today's thunder and lightning."

"exactly"

Clarence was stunned and said in surprise: "What?"

"I said you were right, but so what?

Clarence, actually you don’t have to worry. When I came to this world, I appeared in the Elf Forest. It happened to be Nicole who saved me. Only Nicole and Anthony the Great Sage knew about this.

Therefore, you don’t have to worry about this matter, because the decision not to disclose my identity to the outside world is also the intention of Great Sage Anthony. "
