Abstract
The word electromagnetic field is the combination of electric and magnetic fields. An electromagnetic field is sometimes known as EM field, and it is generated when charged particles are at rest or in motion. There are two types of charges in elementary physics, namely the positive charge and the negative charge. An electric field depends mainly on these charges. The rate of change of charge generates current, which produces a magnetic field. A field is a special distribution of a parameter, which may or may not be a function of time. Time varying electric and magnetic fields are joined together to form an EM field. The time-dependent EM field produces a wave that radiates from the source.
