Before Long Xi could take a closer look, his sleeve moved slightly, and a hidden weapon flew out of his sleeve and flew directly towards the big black stone.

He was taken aback, and subconsciously reached out to grab it.

"Don't move!"

Angelica was born, and her hand also reached over and grabbed Long Xilin's hand.

Long Xilin was stunned: "What's the matter?" ”

Angelica shook his head: "It's nothing, I'm afraid that you will touch the line over there." ”

Angelica said, pointing to the coil and the line connected to it: "There is an electric current there, if you touch it, you will be electrocuted." ”

Angelica said, cautiously walked over, pulled the hidden weapon from the magnet, turned around and walked to the door, and put the hidden weapon on the ground.

"Electricity? What is Current? Long Xilin was still confused by this new term that had never been heard of, and Angelica had already walked back.

Angelica thought for a while and gave him a relatively simple and easy-to-understand example: "It's thunder and lightning, you have seen thunder on a rainy day, when thunder and lightning are combined, the extremely bright light is the current, but the current of thunder and lightning is very strong, so strong that it can split trees and kill people." ”

This example is very simple and easy to understand, and Long Xilin immediately understood.

He stretched out his finger and pointed to the coil that kept cutting back and forth between the two big rocks, and asked, "You mean, that line has the same energy as thunder and lightning?" But why can't you see anything on it, as if there was nothing? And thunder and lightning, but it is so dazzling? ”

"The intensity of the two is different." Angelica said, taking out a pair of glasses from his bag.

She handed it to Long Xilin, "If you want to feel the existence of electricity, just put on these glasses, and you can see it." ”

This eye is redeemed by Angelica from the system, and some phenomena can be seen that are invisible to the naked eye.

Long Xilin reached out and took the glasses, looked down, and then put them on the bridge of his nose.

The moment the glasses were put on, Long Xilin immediately saw the two black stones, and on the coil, there were some small lights flowing in a flash, surging in one direction.

That kind of extreme visual perception made him stunned.

"See?"

Angelica saw that he did not move, so he asked.

Long Xilin nodded: "I saw that many small white points of light, forming thin rays of light, moved around that coil. ”

Angelica nodded: "That's it." ”

"It's just that why does this coil slide from side to side to produce such a magical current? Is there power in this coil, or is there a mysterious power on these two magical stones that we can't see? ”

Angelica pointed to the two magnets: "Between these two stones, called magnets, there is a magnetic field, and as long as that coil cuts the magnetic field lines in the magnetic field, an electric current can be generated. ”

Long Xilin understood a little: "In other words, the magnetic field released the energy in the coil?" ”

Angelica tilted his head and thought about it, and shook his head: "No, it's a magnetic field that converts kinetic energy into electrical energy, and the reason why our coil can move is because the waterfall outside hits the water wheel, and the rotation of the water wheel drives the rotation of a series of gears, and the effect of the magnetic field is to convert those kinetic energy into electrical energy." ”

Angelica said, stretched out his hand and pulled Long Xilin, and the two walked out of the small room together.

Angelica closed the door and turned around, Long Xilin still looked at the small house in a daze.

Angelica added: "The current travels along the wire......"
