Sagot :
Answer:
It is important because Electromagnetism is a branch of physical science that involves all the phenomena in which electricity and magnetism interact.
This field is especially important to electronics because a magnetic field is created by an electric current.
The study of EM is essential to understanding the properties of light, its propagation through tissue, scattering and absorption effects, and changes in the state of polarization.
Everyday life is pervaded by artificially made electromagnetic radiation: food is heated in microwave ovens, airplanes are guided by radar waves, television sets receive electromagnetic waves transmitted by broadcasting stations, and infrared waves from heaters provide warmth.
Explanation:
ANSWER:
I think it is important so we can understand the properties of light, its propagation through tissue, scattering and absorption effects, and changes in the state of polarization. Thes are also used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays. Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur.
