It is one of the four fundamental forces of nature (the others are gravitation, weak interaction and strong interaction). The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges (currents) these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz force law. From a classical perspective in the history of electromagnetism, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner whereas from the perspective of quantum field theory, the field is seen as quantized, being composed of individual particles. In the past, electrically charged objects were thought to produce two different, unrelated types of field associated with their charge property. An electric field is produced when the charge is stationary with respect to an observer measuring the properties of the charge, and a magnetic field as well as an electric field is produced when the charge moves, creating an electric current with respect to this observer.

An inorganic compound is a chemical compound that is not an organic compound.There is no clear or universally agreed-upon distinction between organic and inorganic.
