Do you know lightning locking? A person or object that is within the range of lightning strike or is struck by lightning is called "locked in by lightning". Don't believe it! Some netizens have personally experienced it!

In this case, the high voltage and current of lightning may cause harm or damage to human bodies and objects. So, how to do it when locked in by lightning? Here comes the knowledge of life preservation!

The correct approach is: 1. Immediately leave the original location and ensure that you are not the highest point in the area. 2. Hide inside the car.

What is the Faraday cage principle?

Faraday cage was invented by British scientist Michael Faraday in 1836. It is also called "Faraday barrier" and "shielding box". It is a closed object made of conductive materials that looks like a cage. The main principle is that under the external environment with electrostatic field or electromagnetic radiation at the moment of change, due to the free movement of electrons on the surface of the conductor, the effect of the electric field may only cause an instantaneous displacement of electrons in the conductor. However, overall, this displacement is very small, so the external electric field has almost no effect on the internal electrons. Thus achieving the effect of shielding external electric fields and electromagnetic waves. Because of the excellent protective effect of Faraday cage, it is widely used in modern communication and electronic physics.

I hope the above cold knowledge can be useful when you encounter an emergency.

I also hope you will never encounter the terrifying situation of being locked in by lightning!

From an ethical and moral perspective, life is considered sacred and should be protected and cherished. Life is truly precious, everyone has only one life, and we must respect life!
