Electromagnetic radiation generation
- Nov 17, 2018 -

Any alternating current forms an alternating electric field around it, and the alternating electric field produces an alternating magnetic field. The alternating magnetic field produces an alternating electric field. The alternating electric field and the alternating magnetic field are perpendicular to each other. The source is centered alternately to the surrounding space and propagates at a certain speed, called electromagnetic waves. In the process of electromagnetic waves propagating outward, electromagnetic energy is transmitted out. This phenomenon is called electromagnetic radiation. In general, radar systems, television and broadcast transmission systems, radio frequency induction and medium heating equipment, radio frequency and microwave medical equipment, various electrical processing equipment, communication transmitting stations, satellite earth communication stations, large-scale power stations, power transmission and transformation Equipment, high-voltage and ultra-high-voltage transmission lines, subway trains and electric trains, and most household appliances can produce electromagnetic radiation sources of various forms, frequencies and strengths. There are five kinds of people who pay special attention to electromagnetic radiation pollution: those who work in or near the above environment; those who often use computers, electronic instruments, medical equipment, office automation equipment; workers who live in modern electrical automation environments; Patient of the beater; pregnant woman living in the above environment.
