induction coil

n.
A transformer, often used in automotive ignition systems, in which an interrupted, low-voltage direct current in the primary is converted into an intermittent, high-voltage current in the secondary.

induction coil

n
(Electrical Engineering) a transformer for producing a high voltage from a low voltage. It consists of a cylindrical primary winding of few turns, a concentric secondary winding of many turns, and often a common soft-iron core. Sometimes shortened to: coil

induc′tion coil`


n.
a transformer that consists of two concentric coils wound on the same core and is used for producing high-voltage alternating current from low-voltage direct current.

induction coil

A type of transformer that changes a low-voltage direct current to a high-voltage alternating current. Induction coils are used for many purposes, such as firing spark plugs in automobile engines and starting oil burners.
