(physics) one of a pair of flat coils, having equal numbers of turns and equal diameters, arranged on a common axis and connected in series; used to obtain a nearly uniform magnetic field without the use of a long solenoid

A telecoil.

A modified Tesla coil used to produce high voltage arcs and discharges.

A mosquito-repelling incense, usually shaped into a spiral, and typically made from a dried paste of pyrethrum powder.

plural of coil winder

(electrical engineering) An electromagnet, consisting of a coil of wire through which a current flows, used to generate a magnetic field in an electromagnetic machine, typically a rotating machine such as a motor or generator.

(electricity) a coil of wire designed to provide impedance in an electric circuit

An electric coil of small resistance and large inductance, used in an alternating current circuit to impede or throttle the current, or to change its phase.

plural of coil gun

An electrical device for measuring alternating current (AC) or high-speed current pulses. It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The whole assembly is then wrapped around the straight conductor whose current is to be measured.
