electromagnetic field

   Also found in: Dictionary/thesaurus, Medical, Acronyms, Encyclopedia, Wikipedia 0.01 sec.

electromagnetic field

In physics, region in which a particle with an electric charge experiences a force. If it does so only when moving, it is in a pure magnetic field; if it does so when stationary, it is in an electric field. Both can be present simultaneously. For example, a light wave consists of continually oscillating electric and magnetic fields.
