The most difficult thing about large generators is permanent magnets, and natural magnets cannot make large generators.

A high-energy magnet must be crafted first.

"Time is pressing, Orange, you get a now! Remember, if you want a, you want a thick and big kind, Yan Fa, you accompany you to move, Lime, you go to your uncle to ask for copper wire, I asked him to do a lot, Yang Chi, you go to your father's side to get some silver, move fast! When you're ready, go find me on the hillside outside the camp! ”

Everyone understood these orders, and they immediately took action.

Lightning... Serve me, help me make a high-energy magnet!

Ma Qiang walked out of the laboratory and said to Xian Yufu, who was guarding outside, "Brother Xian Yufu, take people and me to the hillside outside the camp, bring craftsmen and materials, and a simple boiler, and we have to make a shelf." ”

"What? Ma Lang wants to ask the lightning to come down? When Yue Liang heard Lu Qinglime say this, he directly dropped the hammer in his hand to the ground in fright.

This is the ability to ask lightning, it's not immortal art, so what?

"Brother Xiao Ma said to hurry up, Uncle Father-in-law, tell me where the copper wire is?" Lu Qingling was so anxious that she was about to jump to her feet, watching that the sky outside was getting darker and darker, and lightning was about to come.

If it was because he missed the time to invite lightning, Lu Qingling would feel uncomfortable thinking about it.

"The copper wire was painted and dried a few days ago, I'll go with you, this matter of asking God can't be sloppy, a few of you, go to move the copper wire together, a few of you, go to the canteen Gao Yu to ask for a pig's head, a cow's head and a sheep's head, by the way, take some soju, and incense!"

Yue Liang had an expression that you didn't take the gods too seriously, and then ran to the cliff with a large group of people.

On the hillside, Ma Qiang and Lu Yun were directing craftsmen to build wooden frames and dig holes, when they suddenly saw Yue Liang and a large group of people running over, and couldn't help asking, "Uncle Yue, what's wrong with you?" ”

Yue Liang gasped, looked at Ma Qiang with an annoyed expression, and complained, "You have to invite God, and you also have to prepare something, you wait, I have already asked someone to prepare sacrifices." ”

Sacrifice??

Why Sacrifice???

Ma Qiang's mouth opened slightly, and he didn't know what to say for a while.

Lu Qingcheng rushed over with a steel rod half jumping and half running, Ma Qiang looked at the stick, Lu Qingcheng's hand couldn't hold it, it was two meters long, and he couldn't help but look at Lu Qingcheng's arm.

Does this little girl have so much strength? I'm afraid this thing is no less than 200 pounds.....

Then look at the tired panting but empty-handed face hair in the back, tsk, tsk, shame, brother.

When Yue Liang saw this, his eyes were about to pop out.

"What are you carrying this thing for? Isn't that my gift back then? ”

I said Uncle Yue... Why are you giving a little girl a hard stick...

"I'm going to use it, Qingcheng, you've found a good stick, it's quite suitable."

"Uncle Yue gave me the one to exercise my arm strength back then, anyway, I don't need it now, you use it first."

You cow... Use this thing to build your arm strength.

Winding copper wire is very simple, Ma Qiang taught for a while, a few craftsmen who came with him will be there, Yan Rou also took people to set up a platform, and at this time, Yang Chi rushed over.

"This is silver..."Yang Chi handed it to Ma Qiang, and after Ma Qiang took it, he asked people to melt the silver, and then make the shape of a spear head and fix it at one end in order to better conduct electricity.

At this time, the wind was already blowing, and on the hillside, a big stick was facing the sky straight up, like a. Ahem.. Indecent things.

"The sacrifice is coming!"

Seeing Yue Liang being serious and Gao Yu placing offerings, he even brought incense and candles.

Ma Qiang slapped himself in the face, and this scene was unwatchable.

A good scientific experiment adds a touch of clarity to the atmosphere.

"Uncle Yue, this is really not needed, this thunder and lightning can be attracted if I say it's possible."

"I believe you, but you borrowed God's thunderbolt, so you can't pay something back? As the old saying goes, there is borrowing and repaying, isn't it difficult to borrow again, if you don't borrow it back, God will come and take your things by yourself and leave. ”

Yue Liang has already begun to lead everyone to worship heaven and earth, Lin Zhi has also learned to kowtow there according to Bai Yan's head, and Lu An and others who heard the news have also come, it seems that before the evening, most of the people in the Red Star Camp should know that Ma Qiang wants to borrow thunder and lightning.

Looking at this scene of incense, I almost came to a Taoist monk or something.

It's over, it's completely inexplicable!

Ma Qiang sighed, what do you like.

"Boom!!"

Thunder rang out from afar, and lightning began to brew in the sky, and Ma Qiang hurriedly told everyone to leave the hillside and stay in the house at the bottom of the hillside, not to walk around, let alone stay under the big tree.

"Lightning! It's lightning!! ”

"God, today we borrowed your lightning from the Red Star Camp, and we will definitely worship every day in the future, and we dare not slack off."

Ma Qiang didn't care about Yue Liang and a few other people muttering there, and began to teach on the spot.

"As I said before, there is a thing called electric charge in heaven and earth, and the charge is divided into yin and yang, and the yin and yang charges will attract each other, and in the clouds that are going to rain, there will be a yin charge at the bottom of the cloud, a yang charge at the top, and a yang charge on the earth, and the yin charge will be attracted by the earth or the top of the cloud, forming an electric current.

But this attraction is like two people want to get married, they need a matchmaker, I call this kind of thing that can connect two charges like a matchmaker is called a conductor, air is not a suitable conductor, but iron is, steel is actually a kind of iron, in addition to iron, gold, silver and copper are also conductors, and the conductivity is better than iron, so if you are in a thunderstorm, you must not walk with bare metal utensils, otherwise it is easy to attract lightning. ”

"This Thor is still greedy for money."

The craftsman who was listening to the lecture on the side couldn't help but say.

"Yes, I also know that gold and silver are better than copper coins, and the gods in the sky are too snobbish."

"Don't talk nonsense, be careful of heavenly punishment!"

Ma Qiang listened to the discussion of this group of people, and only felt that the three views were ruined, can he still explain it like this? The popular science I just now has become Thor's love of money?

Ma Qiang seemed to see a bird in the sky with a hammer and wings, and he looked half dead.

"Lightning has struck!! Look! ”

"Boom!!"

One after another lightning slashed towards the big black rod that was erected, Ma Qiang continued to explain, "I told a few of you before that there are magnetic domains in iron, and magnetic domains have directions, and the direction of magnetic domains in ordinary iron is chaotic, but if it is washed by a high-voltage current like lightning, the direction of the magnetic domains will be unified, and the iron rod will be electromagnetized and become a big magnet.

But iron cannot become a permanent magnet, the meaning of a permanent magnet is a magnet forever, because there is a thing called the correction force, steel has a larger correction force, and the coercivity of iron is smaller, the greater the correction force, the greater the magnetic force needed to make it become a magnet, but the more difficult it is to lose, on the contrary, the easier it is to become a magnet, the easier it is to lose.

Okay, let's wait for this rain to pass, and then go to acceptance. ”

Everyone looked at the steel rod that was constantly being struck by lightning in a daze, and the steel rod with the tip of the silver spear seemed to have some great fault, and almost every few minutes a lightning bolt struck it.

Bai Yan looked at this scene lying on the ground and trembled, a spirit beast like him was the most afraid of such a power of heaven and earth.

And other people's minds have already made up the process of building some legendary divine weapons, what thunder god strikes iron, wind blows wind, fire god burns fire, water god quenches....

Mr. Ma is not going to do any magic weapon, right?
