Electromagnetic, physical concept is one of the substances in the performance of the electrical and magnetic properties collectively. Such as electromagnetic induction, electromagnetic wave and so on. Faraday discovered electromagnetic yes. Electromagnetic  circuit breakers  because motion charge fluctuations. The formation of a magnetic field, so all electromagnetic phenomena are inseparable from the magnetic field.  electric transformer  is the study of the interaction of electromagnetic and electromagnetic phenomena, and laws of physics and applied branches. Maxwell varying electric  Air circuit breaker  a magnetic field on the assumption that the entire electromagnetic laid the theoretical system, the development of a significant impact on modern civilization from electricians and electronic technology, a profound impact on awareness of the idea of ​​the material world. .
