What exactly is electricity?

This is really hard to explain or explain.

Because there is no electronics at all now.

Moreover, Taichang is not an expert in electricity, and he is not even a major in mechanics and electrical.

Fortunately, he has learned basic physics, but he still remembers some experiments.

For example, the experiment of magnetic lines.

Electronics cannot be seen without professional equipment, but magnetic lines can be seen through a small experiment.

This experiment is actually very simple, and almost everyone in later generations can do it.

However, no one has seen or thought of it these days.

When Taichang led everyone into the temporary laboratory, everyone was confused.

Glass, wood, magnets, copper wires, iron powder......

These things are combined together, and it is difficult for people these days to be confused.

What exactly does the emperor want to do?

Taichang looked at the laboratory environment roughly and then solemnly said: "Yaoguang, Mizhi, doing experiments is an important means for us to study things. In the future, you must establish several professional laboratories and train a group of experimental personnel. This investment is worth it."

When everyone saw his solemn expression on his face, they thought he was going to introduce what the experiment was for. Unexpectedly, he went to the laboratory again!

This is somewhat inexplicable.

Everyone is a little confused. What does it mean to invest so much is worth it?

The things that the emperor ordered to prepare seemed to be of little value, at most, only a few magnets and rolls of copper wire were worth a little money.

All of these are just a few taels of silver, and the emperor actually said that it is worth the investment!

Is the amount of silver worth more for the emperor?

Cheng Jiashuo couldn't help asking: "Your Majesty, what do you mean by the professional laboratory need and how much money will it cost?"

Taichang said without hesitation: "What is needed? This is your business. As for how much money you need, you can invest as much as you need. Tens of thousands of taels, hundreds of thousands of taels, or even millions of taels."

Cheng Jiashuo was stunned when he heard this.

Millions of taels!

What does it cost millions of taels?

He thought that experimenting is like this now, and he just wanted to find something to try.

As for experimental equipment, laboratory equipment, experimental personnel, experimental environment, etc., he has no idea at all.

Fang Yizhi couldn't help but be stunned when he heard this.

He couldn't think of anything that would cost millions of taels.

Cheng Jiashuo couldn't help asking, "Master, do experiments really cost so much?"

Taichang thoughtfully when he heard this: "As long as it is really needed, what's the point of spending millions of taels? I'll pay tens of millions of taels. The more you spend, the happier I'll!"

Perhaps, it is time to consider establishing a special laboratory or research institute for these people.

As for what to study, it is too simple.

There were so many things in his mind that these people had studied.

As long as the corresponding results can be produced, he will really produce tens of millions of taels!

The more you spend, the happier you are, it’s not a joke, because the more you spend, the higher the things you develop!

For example, if anyone can develop a mobile phone for him, what is the point of tens of millions of taels?

Thinking of this, he rolled up his sleeves and said, "Okay, let's do this experiment first. We will discuss it later and build several research institutes."

Uh, didn't you mean a special laboratory?

Why has it become a research institute again?

Cheng Jiashuo's face was full of confusion.

Fang Yizhi looked at the things on the big table with great interest.

Taichang directly chose a magnet that was ground into a long strip, put it in the middle of the large table, and then placed two wooden squares slightly thicker than the magnet on both sides of the magnet, then picked up a piece of glass and covered it up.

Immediately afterwards, he asked, "Mizhi, do you know why magnets can absorb iron?"

How can I know this?

Fang Yizhi shook his head without hesitation and said, "Emperor,

The students don't know."

Taichang nodded slightly, and then solemnly said: "The reason why magnets can absorb iron is because it has a magnetic field. This experiment is to let you see what the magnetic field looks like."

After saying that, he directly scooped a spoonful of iron powder and poured it on the glass, then took the smallest wooden square and gently scraped it a few times, scraping the iron powder on the glass into a thin layer.

What is the emperor doing?

Cheng Jiashuo's face was still confused.

Fang Yizhi stared at the iron fans on the glass.

Immediately afterwards, Taichang said solemnly: "I'm optimistic."

After saying that, he took the wooden square and gently tapped the glass.

A miracle happened. The iron powder on the glass slowly gathered into arcs after arcs, and then synthesized into ovals after ovals, and finally became a shape that was symmetrical like butterfly wings.

Taichang pointed to the pattern on the glass and said, "Mizhi, do you see it? This is the magnetic field formed by the magnet."

Fang Yizhi naturally saw this.

However, this thing is too abstract, and no one can tell at a glance what's going on!

Even if he is genius, he will never be able to figure it out at once.

So, he just frowned and pondered at the pattern on the glass, and did not speak.

OK, it seems that it needs to be more intuitive.

Taichang thought for a while, then picked up another long magnet of about the same size and lifted it under the glass.

It turned out that the magnet was naturally sucked in a flash.

He held two magnets sucked together and said to Fang Yizhi: "Want to know why they sucked together?"

Think about it!

Fang Yizhi nodded repeatedly and said, "Students want to know."

Taichang nodded slightly, then pierced the two magnets apart, and put them into the glass from both sides to try. Until he felt that the magnetic force was almost done, he said to Zhizhi: "Mizhi, I just did it. You do it again, start by scraping iron powder."

When Fang Yizhi heard this, he quickly picked up the small wooden square and gently scraped the iron powder on the glass evenly. Then he took the small wooden square and gently tapped the glass.

His observation was really very careful. His actions were almost the same as what Taichang had just done, and there was no omission in the middle.

This time, the patterns appearing on the glass are corresponding arcs one after another, and the end of the arc is exactly the ends of the two magnets.

Taichang then explained: "See, the magnetic fields of the two magnets overlap, so they will suck together."

Seeing this, Fang Yizhi couldn't help but nodded thoughtfully.

Immediately afterwards, Taichang dropped another magnet and put it under the glass, roughly trying the repulsive force on both sides. Until he felt that the repulsive force was almost done, he said with wisdom: "Minzhi, do it again."

Fang Yizhi heard this and quickly picked up the small wooden square, gently scraped the iron powder on the glass evenly, and then took the small wooden square and gently tapped the glass. uu Reading www.uukanshu.com

This time, the pattern that appeared on the glass seemed to be a collision between two magnetic fields, and the magnetic lines on both sides were curled backwards, and no one overlapped.

Seeing this, Fang Yizhi couldn't help but reveal a look of suddenness.

Taichang then introduced: "This is the magnetic field. As long as the iron is close to the magnetic field, it will be sucked by the magnet."

Well, there seems to be no suitable small iron blocks to demonstrate here.

Taichang was stunned for a moment, and then said to Cheng Jiashuo: "I ordered someone to find a few small iron nails."

Cheng Jiashuo quickly waved to an old carpenter.

Soon, the old carpenter ran over with a normal iron nail.

Taichang thought about it and stuffed another magnet under the glass, and the other one was put aside.

He picked up the small wooden square and scratched it and knocked it again. The magnetic field or magnetic line of force of the magnet appeared on the glass again.

Immediately afterwards, he picked up a small iron nail, stuffed it under the glass, and slowly pushed it towards the magnet with a small wooden square.

At the beginning, the small iron nail had no reaction. As soon as it approached the magnetic field range, the small iron nail was sucked by the magnet.

This time, Fang Yizhi finally nodded repeatedly and said, "Student understands."

very good.

The next step is to use magnetic fields to generate electricity.

Taichang looked at the materials on the table and suddenly became stunned again.

This seems to be impossible!

The materials on the table are fine and are enough for experiments. The problem is that it is not possible to do this experiment with these materials.

The key to using magnetic fields to generate electricity is to make the magnet or coil rotate. If neither of these two things can be rotated, it is impossible to demonstrate using magnetic fields to generate electricity!
