Wizard: I brought the wrong system

"Most objects contain a kind of small particles called electrons. Normally, those electrons are static. If you compare them to sections of calm pools, then lightning is a raging waterfall, and ordinary electric sparks and electric currents are Creeks, rivers."

No one knows whether magic crystals, magic stones and other items contain electrons, so Yarrow said most of the items.

Otherwise, matter normally composed of atoms must contain electrons.

"Under the action of gravity, the water flow will fall from a high place to a low place. To create an electric current, it is naturally necessary to add a force to the electrons. Only in this way can the electrons flow and form an electric current."

Yarrow didn't do much to explain chemical power generation, otherwise he would probably have to describe what "chemistry" is, and explain clearly what is electron loss and what is electron gain, in order to roughly explain the principle of chemical power generation.

"The magnetic field is a pair of 'hands' that can touch the electrons, and the generator is a fixed magnetic field, like a thin rod that can touch the electrons, allowing people to push the electrons in the object..."

Even though she has read it many times, Heli still can't help but lose her mind.

Electrons, currents, magnetic fields... strange words one by one.

Puddles, streams, hands... Ordinary things that can be seen in daily life.

This is how the comparisons are linked.

Not only did Heli clearly understand what 'current' is, but it also opened a door to a new world for her.

Behind the gate, mysterious and silent.

It's so novel again.

Excited emotions surged in Heli's heart. Like a newborn baby, she looked at this brand new world curiously under her father's warm embrace.

"Lord Yarrow..."

Little Heli took a deep breath to calm down her emotions.

After 'seeing' the outline of the 'New World', Yarrow drew some diagrams of the generator structure for her, and she could get a general idea of ​​it.

"First the fine copper wire."

Copper wire is very ductile, and a large pile of copper wire can be easily made by following the same method of making steel wire, and it can also be made thinner.

"And then gum."

The weather in the past few months has been very cold, so there is not much gum collected. Because of this, when Yarrow made the hang glider, he did not use transparent and bright gum, but left it to Heli as an insulating material. .

Most gums are very good insulating materials. In Yarrow's previous life, many household appliances, wires, sockets, and plugs were covered with gum.

"The resin is heated, and the thin copper wire is soaked and washed in it, so that the surface of the thin copper wire is stained with a thin layer of resin."

The copper wires in the motor are not bare copper wires, they have a thin layer of insulating varnish on their surface, commonly known as enameled wires.

Without this layer of insulation, the current generated by the magnetic field cutting will only flow in these copper rings, and the kinetic energy of the electrons will be converted into heat and light energy and released directly, causing a short circuit in the motor, and no current can be generated.

"Wind the copper wire dyed with gum in a circle, fixed the magnet, and installed the bearing..."

There are many semi-finished products of various parts in the laboratory, as well as many tools for making items, which makes the process of making small Heli very smooth.

When it was late at night, little Heli finally assembled the simple generator.

"Then... give it a try?"

Little Heli's heart is not easy.

"Yeah, an item has been made, why not give it a try?"

Thinking of this, little Heli reached for the rocker bearing.

creak, creak...

The iron rocker swayed constantly on the dead wood frame.

slap, slap...

The two copper wires not far apart suddenly flashed a series of tiny electric lights.

Like a coincidence, almost at the same time, a thunderbolt exploded out of thin air outside the house.

A faint white light appeared in the sky, like a white dragon swimming slowly in the dark night sky.

In the castle shrouded in invisible air pressure.

Some of the sleeping servants suddenly gasped uncomfortably and were jerked out of their sleep.

In the dark corner, the swimming shadow froze in place, and suddenly exploded into a ball of blood.

"Eh? What kind of method is this?" At the same time, a suspicious voice sounded from an unknown location.

The moist cool wind blows the candlelight and shakes it slightly.

Little Heli was obsessed with the faint electric arc, but she didn't know anything about her surroundings.

"This is the electric flower!"

Little Holly stared wide-eyed, curiously looking at the vacancy in the middle of the copper wire.

It's not that she has never seen electric sparks.

According to the method of generating electricity by friction, little Heli had already seen the flickering electric light.

But those flashes were too short.

For a short time, little Heli didn't know whether what she saw was the electric light, or the last light before the electric light disappeared.

Now, she finally saw the real 'electricity'.

Although... it was just a tiny arc.

There was thunder outside the house, but little Heli didn't feel the slightest bit of fear. At this moment, all her attention was focused on that tiny electric arc.

"A single electric arc is so beautiful, so... how amazing would the electric sparks gathered by thousands of electric arcs be?"

Little Heli looked at the copper tag placed aside, at the strong electric sparks depicted on the tag... and those firm and bright eyes.

A sense of accomplishment that is approaching her dream, a key step towards her dream, filled her heart.

"It's not enough, how can a trace of electric arc be enough!"

"Only with more and bigger arcs can it be possible to make the scene in the tag!"

"Is there any way to increase the arc, or like a reservoir... to store this arc?"

Yarrow hadn't taught little Holly about the battery, and she was left to figure it out on her own until Yarrow returned.

"Since copper can be used to create arcs, then... can copper be used for storage?"

Bold assumptions, careful verification, this is what Yarrow often talks about, so little Heli is going to try.

Little Heli paused in her hand, and the flickering electric arc disappeared.

"Let's try it with the copper tag that Master Yarrow gave you!"

"On the hang tag that is already engraved with the pattern of electric sparks, if there are real electric sparks on it, the scene will definitely be beautiful!"

Thinking of this, little Heli connected the two poles of the copper wire to the copper tag.

"Then let's get started!"

Little Heli took a deep breath and shook the rocker bearing beside her.

Clap!

A bolt of lightning went around the window and struck the copper tag!

Boom...!

The thunder is rolling, and the copper tag is generous and shining.

Little Holly was stunned.

There seemed to be many pictures in her eyes.

Strange dolls, ordinary boys, many flat girls who look the same in the water, white houses, towering buildings...

And... the huge stone bridge that little Heli feels somewhat familiar for some reason!

Everything is like a dream, but also like reality.

It's like... within reach.
