ELECTROMAGNETISM A number of turns of wire used to introduce inductance into an electric circuit, to produce magnetic flux, or to react mechanically to a changing magnetic flux; in high-frequency circuits a coil may be only a fraction of a turn. Also known as electric coil; inductance; inductance coil; inductor. SCIENCE AND TECHNOLOGY An arrangement of flexible material into a spiral or helix. |
