Electric field and magnetic field

Electromagnetic fields are made out of photons . The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.

electromagnetic field, a property of space caused by the motion of an electric charge . A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.

Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health .4 Ağu 2016

Electromagnetic fields are present everywhere in our environment but are invisible to the human eye . Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms.

An electromagnetic field (also EM field or EMF ) is a classical (i.e. non-quantum) field produced by accelerating electric charges. It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics.
