Discovery of the phenomenon of electromagnetic induction, electromagnetic field is the greatest achievement

Electromagnetic induction means for magnetic flux induced electromotive force of the phenomenon.
Discovery of the phenomenon of electromagnetic induction, electromagnetic field of one of the greatest achievements. It not only between electricity and magnetism reveals the intrinsic link between  Electric transformer  and magnetism but also for mutual  mcb circuit breaker  lay the foundation for human access to a huge and cheap electricity opened the way, there is great significance in practical. Discovery of the phenomenon of   electri cenergy meter   induction, marking a major industrial and technological revolution soon. Facts have proved that electromagnetic induction in the electrical, electronic technology, electrification, automation widely used for the promotion of social productive forces and the development of science and technology has played an important role.
