the coupled electric and magnetic fields that are generated by time-varying currents and accelerated charges.
a field of force associated with a moving electric charge equivalent to an electric field and a magnetic field at right angles to each other and to the direction of propagation
- Electromagnetic energy
noun a form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space Examples There are many forms of electromagnetic energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
- Electromagnetic force
electromagnetic force (ĭ-lěk’trō-māg-nět’ĭk) The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena. Like gravity, the electromagnetic force has an infinite range and obeys […]
noun, Electricity. 1. the induction of an electromotive force by the motion of a conductor across a magnetic field or by a change in magnetic flux in a magnetic field. Production of an electric current by changing the magnetic field enclosed by an electrical circuit. The most common use of electromagnetic induction is in the […]
- Electromagnetic interaction
noun 1. (physics) an interaction between charged particles arising from their electric and magnetic fields; its strength is about 100 times weaker than the strong interaction See interaction (sense 2), electroweak interaction
