Introduction to electromagnetics

Electromagnetics is the branch of physics in which electric, magnetic fields and interaction of electric, magnetic fields are studied.

Applications of electromagnetics

The various applications of electromagnetics include microwaves, antennas, electric machines, satellite communication, bioelectromagnetics, electromagnetic interference and compatibility, electromechanical, nuclear research, fiber optics, energy conversion and remote sensing.


1. For melting, surface hardening and for soldering operation electromagnetic fields are used.
2. Electromagnetic energy is used in agriculture to change the taste of the vegetables by reducing acidity.

Electromagnetic devices

The various electromagnetic devices include transformers, electric relays, TV, radio, telephones, electric motor, transmission lines, antennas, optical fibers, radars and lasers. The design of these devices requires thorough knowledge of the laws and principles of electromagnetics.
