Static electricity
Q: What is static electricity?
During this rotation on the earth, a kind of magnetic field is generated. This magnetic field interacts with the earth's water and sunlight, and it generates static electricity. The generation of static electricity will probably stay on the metal.
How can static electricity be generated? There must be a movement (action). This is a very delicate one. So when you arrive in the United States in a very dry place, many people dare not press the elevator and they will be electrocuted. That is static electricity. Between the rotation of the earth and water vapor, it is easy to generate static electricity. When there is a lot of static electricity, as the water vapor rises to the sky, it will generate a connection effect. Each static electricity adds up to a high voltage of more than one million connections volts, the electricity is very much, it called air discharge.
