Electromagnetism is the study of the interaction of electromagnetic and electromagnetic phenomena

Electromagnetism is the study of the interaction of electromagnetic and electromagnetic phenomena, and laws of physics and applied branches. Early on, the phenomenon was considered to be due to magnetic and electrical phenomena independent of the other, and also because the magnetic own development and applications such as  mcb circuit breaker  materials and magnetic technologies, new magnetic effect and magnetic phenomena such as the discovery and application etc., making the magnetic  electric meter  to expand, so magnetic in practice it as a parallel and electrical disciplines to study it.
Electromagnetics from the original two mutually independent science (electricity, magnetism) develop into a full branch of physics disciplines, is mainly based on two important  mcb circuit breaker  that the current changes in the magnetic field effect and electrical effects. Both experimental phenomena, coupled with Maxwell varying electric field generates a magnetic field on the assumption that the entire electromagnetic laid theoretical system, the development of a significant impact on modern civilization from electricians and electronic technology.
