Daming: The system rejected my request for salted fish

Although the shape of the magnet in Wei Wu's hand is a bit strange, the effect is the same.

As everyone was looking at the magnet, Wei Wu spoke again:

"If you want to make a generator, the most important thing is magnets, but the natural magnets that are mined won't work."

"Natural magnets don't have enough magnetic force to generate electricity, so we have to artificially make stronger magnets that are more effective."

"Electricity and magnetism are naturally inseparable, so to make strong magnets you must use electricity, extremely strong electricity!"

After listening to what Wei Wu said, Sun Chang had an idea.

"Mr. Vice President, so when you said you wanted to be struck by lightning, does that mean you only need to let the iron be struck by lightning to turn it into a strong magnet?"

"Yes and no!"

Wei Wu answered simply.

Hearing this answer, Sun Chang's face showed confusion again.

Yes and no, so is it or not?

At this moment, Wei Wu explained again:

"Lightning alone is not enough. We need to use the energy of lightning to form a strong magnetic field to magnetize the iron."

"Then how can we use lightning to form the magnetic field you mentioned?"

After listening to Wei Wu's explanation, Sun Chang couldn't wait to ask.

Wei Wu simply answered with two words.

"Copper wire!"

After saying this, Wei Wu continued to explain:

“It’s important to first create a cast iron block and wrap the copper wire around it in a right-hand spiral.”

At this point, Wei Wu briefly explained the right-hand screw rule (Ampere's law).

In fact, these theories are not difficult and are covered in high school physics textbooks.

At present, we just need to let the craftsmen know that they should do this. As for why they should do this, we can study it slowly in the future.

After explaining the right-hand screw rule, Wei Wu talked about the production of strong magnets again.

"Remember, the copper wire must be insulated. This means applying varnish to the copper wire first. This is called enameled copper wire."

"Because cast iron is also a conductor, once the bare wire comes into contact with the cast iron, the current will not be able to form a magnetic field to magnetize the cast iron."

"After doing all this, all you have to do is tie the cast iron block to the top of the wood and stick it on the top of the mountain where it's most likely to be struck by lightning."

The craftsmen in the audience listened carefully and took notes of Wei Wu's words on paper with pens.

After everyone stopped writing, Wei Wu continued:

"If you want to make a generator, strong magnets are the most important thing. The more they are, the better, so they can be used as a backup later."

"So, after I leave the capital, you should follow my instructions and make more magnetized cast iron blocks in advance."

"Whenever there's a thunderstorm, just take them out, keep as much distance as possible, and wait for them to be struck by lightning."

As soon as Wei Wu finished speaking, Sun Chang immediately expressed his opinion:

"Don't worry, Vice President. Our blacksmith team will definitely get this done. We'll be able to make the generator when you return!"

"Well, I also believe you can do it!"

Wei Wu responded, then turned to look at Wu Qiang.

"Wu Qiang, regarding the generator issue, in addition to the strong magnets that the blacksmith team is responsible for, your construction team also has a task."

"I need you to use steel and cement to select a good location by the river and build this building."

"I call this a turbine hydroelectric power station. It can use flowing water to generate electricity, so it must be built by the river."

As he spoke, Wei Wu picked up a pen and began to draw on the paper hanging on the wall behind him.

But what he was thinking in his heart was that he would have to get the chalk and blackboard out later, which would be much more convenient.

Not long after, Wei Wu drew a building that looked like the number 6 and a musical symbol.

"See? Just lift up this valve flapper, and water will flow into it and into this circular area."

"In the middle of the bottom of this location, we need to build a turbine like a propeller to use the water flow to make it rotate and generate electricity."

"But now we don't have strong magnets. Your construction team just needs to familiarize themselves with how to build this structure first."

Having said that, Wei Wu emphasized one sentence specifically.

"Because we need to utilize the potential energy of the water flow, you must remember that the best location to build is a low-lying area."

"There needs to be a certain level of drop between the water inlet and outlet to effectively utilize the water flow. Do you understand?"

Wu Qiang nodded seriously, keeping Wei Wu's words firmly in mind.

Seeing how serious he was, Wei Wu showed a satisfied look on his face, and then he looked at the other craftsmen below the stage.

"Ladies and gentlemen, the advent of the steam engine means we have entered the steam age, where we no longer need to rely on human and animal power."

"But this is just the beginning. I have to tell you that if we can work together, we can make the generator."

"Then, under the leadership of our Academy of Science and Technology, Daming will officially enter the electric age, a brand new era."

"In this era that is feared by foreign races and envied by foreign nations, even after a thousand years, humans will not be able to escape the need for electricity."

“And you guys!!”

Having said that, Wei Wu raised a finger and swept it across the front of the craftsmen.

"You will be the founders of this era. Together with the Academy of Science and Technology, you will be remembered through the ages and worshipped by future generations!!"

As long as one is a human being, there is no one who does not want to leave his name for eternity, just like netizens in later generations.

Even just opening a single page of the family tree is enough to make them excited and fight the devils to the death!

For these craftsmen, the principle is the same.

So after Wei Wu finished speaking, these people became as excited as if they had been injected with chicken blood.

After all, they had already built the steam engine, and the facts proved that Wei Wu had never made any promises to them.

Since the steam age can be realized, the electric age must be realized as well.

Then in the future, they will surely be recorded in history like the ancient sages.

Even Wei Wu, a man from later generations, was excited because he created this era with his own hands.

How could these craftsmen not be excited!

But at this moment, Song Zhong on the side suddenly stood up and poured a basin of cold water.

"Mr. Vice-President, whether it's a large steamship or powerful magnets and turbine power generation, it requires a large number of people."

"Our Institute of Science and Technology doesn't have enough staff right now!"
