A cold knowledge that can save your life!

Do you know about lightning lock? A person or object in range of or struck by lightning is called "locked by lightning". Don't ever disbelieve it! There are users who have experienced it firsthand!

In this case, due to the high voltage and current of lightning, it may cause injury or damage to humans and objects. So, how to do in the case of being locked by lightning what to do? Here comes the knowledge to save your life!

The right thing to do is: 1. Leave your spot immediately and make sure you are not the highest point in the area. 2. Duck into your car.

What is the Faraday cage principle?

A cold knowledge that can save your life!

Faraday cage (Faraday cage) is invented by British scientist Michael Faraday in 1836, also known as the "Faraday barrier", "shielding box", it is a closed object made of conductive material with the appearance of a cage. Its main principle is that in the external environment with electrostatic fields or changes in the instantaneous electromagnetic radiation, due to the electron free movement on the surface of the conductor, the role of the electric field may only cause the electrons in the conductor to produce a momentary displacement, but in general, this displacement is very small, so the external electric field has almost no effect on the internal electrons. Thus, the effect of shielding the external electric field and electromagnetic waves is achieved. Because of their excellent protection, Faraday cages are widely used in modern communications and electrophysics.

I hope the above cold knowledge will come in handy when you encounter an emergency.

And I hope you never encounter the scary situation of "locked by lightning"!

From an ethical and moral point of view, life is considered sacrosanct and should be protected and cherished. Life is precious, and each person has only one life to live, so let's respect it!
