Extremely low frequency electromagnetic radiation from extremely high frequency electromagnetic radiation

Electromagnetic radiation, also known as electronic smog, is transferred from the common space of electric energy and magnetic energy are formed, and the energy generated by the charge  mcb circuit breaker ; for example, the antenna is transmitting a radio frequency signal emitted by the movement of electric charge is generated  electric transformer  energy. Electromagnetic "spectrum" includes all kinds of  air circuit breaker  radiation, extremely low frequency electromagnetic radiation from extremely high frequency electromagnetic radiation. There between radio waves, microwaves, infrared, visible and ultraviolet light, etc. RF part of the electromagnetic spectrum in the general definition, refers to the frequency of about 3 kHz to 300 GHz by the radiation.
