The correct way to open the elf

Chapter 140 Seen Through

"Hahaha, Lord Dick is indeed an excellent warrior. Look at his movements, so agile!"

Feng Yu laughed loudly, and everyone else laughed too. Dick blushed and shouted, "Can you blame me for this? Everyone present knew how powerful your wooden-handled grenade was when you were experimenting with it.

Who knows if this thing of yours is like a wooden-handled grenade, which explodes with a bang!"

Feng Yu smiled and said, "Is it okay if I stand closer to you?"

Dick argued, "I'm just... it's just the fault of the experimental weapon. Anyway, it's all because the thing you tinkered with was too powerful."

"That's called a conditioned reflex!"

"Yes, that's the reflex!"

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 connecting copper wire had already turned faintly red just now.

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

But he is just a novice. He has no problem doing small scientific experiments, but if you ask him to explain something, he is completely clueless. It can only be attributed to the fact that this is a high magic world.

Clarence interrupted the two people's idle chatter and said anxiously: "Darren, this is the power of thunder and lightning, right?"

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

Clarence asked everyone's question: "I understand that the steam from boiling water pushes the piston, but why can a magnet plus a copper wire generate electricity?"

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

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

“You see, the magnet attracts 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 an area with dense magnetic induction lines, electricity will be generated inside the metal.

The reason I use so many copper wires is to get more electricity."

Dick said, "What's the use of this electricity? Can it be used to smelt metals like you said?"

"Not only that, electricity is a more widely used energy source than the steam engine, and it is more powerful than the steam engine.

After all, the steam engine is just the application of water vapor, and the television is the embodiment of thunder.

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

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

He connected the copper wire and said to Dick, "Are you going to shake it or not? If not, I will replace you."

Dick was afraid that someone would come up and snatch the wine from him, so he took two steps to the handle and started cranking it again.

As the speed of the generator increased, the rotor of the electric motor over there also slowly began to turn.

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

Feng Yu: "..."

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

As Feng Yu spoke, he unscrewed the connected wires, connected them to a short piece of very thin spiral metal wire, and placed some scraps of paper inside the metal spiral.

He glanced at Dick, who immediately started working hard to crank the generator handle again.

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

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

Electricity is a more efficient way to generate heat to melt metal than using fire to melt metal, and it is also a way to melt stronger metals.”

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

Feng Yu signaled Dick to stop, and Dick let go and said, "Dadi, you can actually harness the power of thunder and lightning. This is truly 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 the elves would think of using magical elements."

Dick asked, "If you want to use electricity to smelt metals, how do you do it?"

Feng Yu said: "Use a bigger magnet, wrap more copper coils, make the generator rotate faster, and generate stronger electricity. But that will require some experimentation in the future."

Nitia asked from the side: "Can electricity be used as a weapon?"

Feng Yu nodded and said, "Of course, direct contact with electricity alone can cause great harm to living organisms. Electricity can also drive many powerful weapons, but that requires more advanced knowledge of electricity."

Seeing that Dick, Clarence and others wanted to ask more questions, Feng Yu quickly waved his hand, because if he asked again, he would be exposed.

He said: "Any kind of power in the world is systematic, 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 research 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 attend the class. "

Everyone reluctantly left the magical machine that could bring thunder, and the students of the institute also returned to their respective rooms. Only Clarence stayed behind and called Feng Yu.

"Darren, come sit over with me. I want to talk to you."

Feng Yu followed Clarence to his office.

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

Feng Yu was stunned and asked, "Why do you say that?"

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

"You're right!"

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

“I said you’re right, but so what?!
Clarence, actually you don't have to worry. When I came to this world, I appeared in the Elf Forest, and it happened that Nicole saved me. Only Nicole and the Great Sage Anthony knew about this.

So, you don't have to worry about this, because the decision not to reveal my identity to the outside world was also the intention of the Great Sage Anthony."
