Daming: The system rejected my request for salted fish

"very good!"

Hearing Wu Qiang's answer, Wei Wu immediately showed a satisfied smile on his face.

Before leaving Beijing, Wei Wu made a lot of preparations and also made arrangements for the design of the generator.

With the help of the architectural master Song Zhong, the design drawings were drawn up and handed over to the blacksmith team.

When it was designed, it took a lot of time to fit the size of the turbine hydroelectric power station.

Fortunately, it was all worth it. The construction team built the hydropower station and the blacksmith team prepared the parts.

Although they didn't know how to assemble it, it was something that only required one experience.

The key difficulty in making a generator is not the manufacturing ability, but understanding how the electricity is generated.

This involves the theory of magnetoelectric induction, where electrical energy is converted from mechanical energy by cutting magnetic lines of induction.

If you don't understand this theory, then even if you conduct experiments for hundreds of years, it will just be a waste of time.

To give a very simple example, in later generations, an ordinary person just needs to study hard in high school.

Then using some simple tools, you can make a simple generator to light up a small light bulb.

What Wei Wu has to do now is to teach them this theoretical knowledge and then let them experiment with it themselves.

So next, Wei Wu directly took out some simple accessories from the system space and began to make a generator with his bare hands.

However, what he is making now is just a small and simple generator, and its main purpose is to teach craftsmen.

For this moment, he opened a lot of express packages before he was able to get all the accessories together.

In addition to small magnets, copper wires and other accessories, Wei Wu also specially prepared a finger-sized light bulb.

Then, Wei Wu picked up a round plate with holes drilled on the edge in front of all the craftsmen.

"This is called a rotor disk. We can make a rotor by attaching magnets to it."

As he spoke, Wei Wu picked up a few small magnets, arranged their polarities alternately on the rotor disk, and then fixed it.

Then he picked up a cast iron ring-shaped stator core and a large amount of copper wire.

Copper wire is wound around an iron core to make a coil, which is then fixed to a base.

Make sure the position of the coil corresponds to the rotor subway, and explain it while making it.

The craftsmen below did not disappoint him. They all took out paper and pen and began to record what Wei Wu said.

Later, during the production process of Wei Wu, craftsmen would stand up from time to time to ask questions that were in their minds.

Wei Wu was very patient about this and answered their questions while he was making the products.

In this way, an hour passed during the explanation, and the simple hand-cranked generator in Wei Wu's hand was completed.

"Okay, this is how a generator works. Cutting magnetic lines of flux converts mechanical kinetic energy into electrical energy."

"What I'm making now is just a simple generator. My purpose is to let you understand the principle of the generator."

"Now, let's see if this generator can generate enough electricity to light up this little lightbulb."

While speaking, Wei Wu connected all the wires, then reached out and grabbed the crank and started to rotate.

Just when all the craftsmen were concentrating, the small light bulb suddenly flashed a bright light.

And as Wei Wu turned the crank faster, the brightness of the light bulb became brighter and brighter.

"Really, really, it's not connected to any power source, and this thing lights up!"

"It's amazing! So this is how electricity is generated. Humans can really control the power of lightning!"

"Using magnets to cut magnetic lines of force can generate electricity. Then more and bigger magnets can generate even more electricity!"
