"Most items contain a kind of small particles called electrons. Normally, those electrons are stationary. If they are compared to sections of calm pools, then lightning is a raging waterfall, and ordinary electric sparks and currents are Streams, rivers.”
No one knows whether magic crystals, magic stones and other items contain electrons, so Yaro said most of the items.
Otherwise, all matter normally composed of atoms must contain electrons.
"Under the action of gravity, water flow will fall from high places to low places. If you want to create an electric current, you naturally need to add a force to the electrons. Only in this way can those electrons flow and form an electric current."
Yarrow did not do much to explain chemical power generation. Otherwise, he would have to roughly describe what 'chemistry' is, and also explain clearly what electrons are lost and what electrons are gained, in order to roughly explain the principle of chemical power generation.
"A magnetic field is a pair of 'hands' that can touch electrons, and a generator is a fixed magnetic field, like a thin rod that can touch electrons, allowing people to push electrons in objects..."
Even though she had read it many times, Heli still couldn't help but lose consciousness.
Electrons, electric current, magnetic field...all unfamiliar words.
Pools, water, hands... ordinary things we see every day.
In this way, the comparison is connected.
Not only did Heli clearly understand what 'current' is, but it also opened the door to a new world for her.
Behind the door, there is mystery and silence.
It's so novel again.
Excited emotions surged in Hurley's heart. She was like a newborn baby, curiously looking at this new world in her father's warm arms.
"Lord Yaro..."
Little Heli took a deep breath to calm down her emotions.
After "seeing" the general outline of the "New World", Yaro drew some generator structural diagrams for her, and she was able to roughly understand it.
“First there’s the thin copper wire.”
Copper wire has very good ductility. According to the same method of making steel wire, a large amount of copper wire can be easily made, and it can also be made thinner.
“Then there’s the gum.”
The weather has been very cold in the past few months, so not much gum has been collected. Because of this, when Yaro made the hang glider, he did not use the transparent and bright gum, but left it to Xiao Heli as an insulating material. .
Most gums are good insulating materials. Many household appliances, wires, sockets, and plugs in Yaro's previous life were covered with gum.
"Heat the gum, soak the thin copper wire in it and wash it once, so that the surface of the thin copper wire is dyed with a thin layer of gum."
The copper wires in the motor are not bare copper wires. They have a thin layer of insulating paint on their surfaces, commonly known as enameled wires.
Without this layer of insulation, the current generated by magnetic field cutting will only flow in these copper circles, and the kinetic energy of the electrons will be converted into heat energy and light energy and directly released, causing the motor to short-circuit and unable to generate current.
"Wrap the copper wire dyed with gum in circles, fix the magnet, and install 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 Little Heli very smooth.
When it was late at night, Xiao Heli finally assembled the simple generator.
"Then... give it a try?"
Little Heli was heartbroken.
"Yes, once an item is made, why not give it a try?"
With this thought in mind, little Heli's hand reached out to the rocker bearing.
Creak, creak...
The iron rocker kept shaking on the dead wood frame.
Bang, bang...
Two sections of copper wire not far apart suddenly flashed a string 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 enveloped by invisible air pressure.
Some of the sleeping servants suddenly gasped uneasily and were suddenly awakened from their sleep.
In the dim corner, the swimming shadow froze in place and suddenly exploded into a ball of blood.
"Eh? What kind of method is this?" A voice of uncertainty sounded from somewhere.
The moist cool breeze blew the candlelight and swayed slightly.
Little Hurley, who was immersed in the weak arc, knew nothing about the things around her.
"This is the electric flower!"
Little Heli's eyes widened and she looked curiously at the gap in the middle of the copper wire.
It's not like she hasn't seen electric flowers before.
According to the method of generating electricity through friction, little Heli had already seen flashing electric light.
But those flashes of light were too short-lived.
It was so brief that 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 real 'electricity'.
Although...it's just a small arc of electricity.
There was continuous thunder outside the house, but little Heli was not afraid at all. All her attention was focused on that tiny arc of electricity.
"A single electric arc is so beautiful, so... how amazing will it be when tens of thousands of electric arcs gather into an electric flower?"
Little Heli looked at the copper tag placed aside, looking at the strong electric flowers depicted on the tag... and those firm and bright eyes.
A sense of accomplishment that she was getting closer to her dream and that she had taken a crucial step toward her dream filled her heart.
"It's not enough, how can a trace of arc be enough!"
"Only with more and larger arcs can it be possible to create the scene in the hangtag!"
"Is there any way to increase the arc, or to store this arc like a reservoir?"
Yaro has never taught little Heli about batteries. Before Yaro comes back, she can only figure out a solution on her own.
"Since copper can be used to create electric arcs, then... can copper be used for storage?"
Make bold assumptions and be careful to verify, this is what Yaro always talks about, so little Heli is ready to give it a try.
Little Heli paused, and the flashing arc disappeared.
"Let's try it with the copper tag given by Master Yaro!"
"If you put real electric flowers on the tag that is already engraved with electric flowers, the scene will definitely be beautiful!"
With this in mind, Xiao 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 on the side.
Snap!
A bolt of lightning actually circled through the window and struck the copper tag!
Rumble...!
Thunder is rolling, and the copper tag shines brightly.
Little Heli was stunned.
Many pictures seemed to appear in her eyes.
Strange dolls, ordinary boys, many flat-looking girls soaked in water, white houses, tall buildings...
And... the huge stone bridge that little Hurley felt a little familiar for no reason!
Everything is like a dream, but also like reality.
It's like... within arm's reach.
