A Course on Essential Elements for Electrical and Computer Engineering .

Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits.

Electromagnetic waves are 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.

Electromagnetic engineers design and develop electromagnetic systems, devices, and components, such as electromagnets in loudspeakers, electromagnetic locks, conducting magnets in MRI's, and magnets in electric motors.
