| electromagnetism |
Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, composed of the electric field and the magnetic field. The electric field can be produced by stationary electric charges, and gives rise to the electric force, which causes static electricity and drives the flow of electric current in electrical conductors. ...

| electromagnetic radiation |
Energy propagated in the form of an advancing electric and magnetic field disturbance. The term radiation, alone, is commonly used for this type of energy, although it actually has a broader meaning. In the classical wave theory of light (or electromagnetic theory) the propagation is thought of as a continuous wavelike disturbance of the electric and magnetic fields, which oscillate in planes orthogonal to each other and to the direction of propagation. ...
