The correct way to open the sprite

Chapter 140

"Hahaha, Master Dick is worthy of being an excellent fighter. Look at this movement, it's so agile!"

Feng Yu laughed out loud, and everyone laughed too, and Dick blushed and yelled, "Is it my fault, no one who was present at the experiment didn't know how powerful your wooden handle grenade was.

Who knows if your thing is like a wooden handle grenade, it rang with a bang! "

Feng Yu smiled and said, "I'm standing closer than you, okay?"

Dick argued: "I'm... anyway, it's the fault of the experimental weapon falling, anyway, it's all because your tinkering thing is too powerful."

"That's called conditioned reflex!"

"That's right, it's this reflection!"

Although Feng Yu was joking with Dick, he was actually shocked, because the arc between the two copper wires was obviously very large, unlike that kind of weak arc, and the connected copper wire was already faintly reddened just now.

Feng Yu is very sure that his generator will never produce such a large arc on the earth.

But he is just a two-handed swordsman, so it's no problem to do small scientific experiments. If you ask him to explain why, he also has black eyes, which can only be attributed to the fact that this is a high-demon world.

Clarence interrupted the chatter between the two, and said eagerly, "Darren, is this the power of lightning, isn't it?"

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

Clarence asked everyone's doubts: "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 electricity generated by the interaction between the magnetic induction line and the 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 lightly shaking the paper twice, the iron powder seemed to be moved by some force and turned into a kind of band. regular patterns.

"You see, a magnet attracts steel by this invisible magnetic force. We call this invisible force the magnetic induction line.

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

And when the metal passes through the place where the magnetic induction lines are dense, electricity will be generated in the metal.

The reason I have so many copper wires twisted together is to get more electricity. "

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

"More than that, electricity is an energy source that is more widely used than steam engines, and it is more powerful than steam engines.

After all, the steam engine is just the use of water vapor, and the embodiment of TV 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 said, he moved out something similar to a generator and placed it opposite the generator.

He connected the copper wire, and said to Dick, "Can't you shake it anymore, if you don't shake it, I will change."

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

As the speed of the generator increased, the rotor of the motor over there also slowly turned.

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

Feng Yu: "..."

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

As Feng Yu said, he unscrewed the connecting wires, connected them to a short section of very thin spiral wire, and put some scraps of paper inside the metal spiral.

He glanced at Dick, and Dick 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. With a trace of smoke, the paper burned itself without 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, it can burn without flames. Melts a lot of metal.

Electricity generates heat to melt metals, which is a more efficient method of melting metals than burning flint, and it is also a way to smelt metals with better strength. "

Before Feng Yu could finish his words, the scraps of paper had already been burned, and everyone saw some reddish spiral wires.

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

Clarence said: "This...is really incredible, how did you think of it!"

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

Dick asked, "What would you do if you wanted to use electricity to smelt metal?"

Feng Yu said: "Use bigger magnets, wind more copper coils, let the generator rotate faster and generate stronger electricity. But that will have to be slowly experimented with in the future."

Nidia asked from the side: "Is electricity used as a weapon?"

Feng Yu nodded and said: "Of course, just direct contact with electricity will also 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, and 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 in the research 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 of the research institute also returned to their respective rooms. Only Clarence stayed at the end and stopped Feng Yu.

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

Feng Yu followed Clarence to his office.

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

Feng Yu was taken aback, and said, "Why do you say that?"

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

"exactly!"

Clarence was taken aback, and said in surprise, "What?"

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

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