Sign in to saveAlso known as EM field, EMF, electromagnetic fields
physical field produced by electrically charged objects
An electromagnetic field is a physical field created by electrically charged objects that surrounds them in space. It matters because it's the fundamental force responsible for how charged particles interact with each other and with light, making it essential to understanding everything from electricity and magnetism to how atoms hold together.

Encyclopedic overview
An electromagnetic field (also EM field) is a physical field, varying in space and time, that represents the electric and magnetic influences generated by and acting upon electric charges. The field at any point in space and time can be regarded as a combination of an electric field and a magnetic field. Because of the interrelationship between the fields, a disturbance in the electric field can create a disturbance in the magnetic field which in turn affects the electric field, leading to an oscillation that propagates through space, known as an electromagnetic wave.
Mathematically, the electromagnetic field is a pair of vector fields consisting of one vector for the electric field and one for the magnetic field at each point in space. The vectors may change over time and space in accordance with Maxwell's equations. The vectors are subject to the rules of special relativity; different observers may determine different vectors.
