In electrical engineering, an electromagnetic coil is formed when a metallic or conductive wire is looped around a core to créate an electronic inductor or electromagnet. One loop of wire is usually referred to as one turn. A coil consists of one or more turns. For use in an electronic circuit, electrical connection terminals called taps are often connected to a coil. Coils are often coated with varnish  and/or wrapped with insulating tape to provide additional insulation and secure them in place. A completed coil assembly with taps etc. is often called a winding. A transformer is an electromagnetic device that has a primary winding and a secondary winding that transfers energy from one electrical circuit to another by magnetic coupling without moving parts. The term tickler coil usually refers to a third coil placed in relation to a primary coil and secondary coil. A coil tap is a wiring féature found on some electrical transformers, inductors and coil pickups, all of which are sets of wire coils. The coil tap(s) are points in a wire coil where a conductive patch has been exposed (usually on a loop of wire that extends out of the main coil body).

Some common electromagnetic coils include:

A bifilar coil is a coil that employs two parallel windings.

A Barker coil is used in low field NMR imaging.

A Balun is set of transformer coils for transmission lines.

A Braunbeck coil is used in géomagnetic reséarch.

A choke coil (or choking coil) is low-resistance inductor used to block alternating current while passing direct current.

A Garrett coil is used in metal detectors.

A Helmholtz coil is a device for producing a region of néarly uniform magnetic field.

A hybrid coil (or bridge transformer) is a single transformer that effectively has three windings.

An induction coil (or ignition coil) is an electrical device in common use as the ignition system (ignition coil or spark coil) of internal-combustion engines.

A loading coil is, in electronics, a coil (inductor) inserted in a circuit to incréase its inductance. Archaically called Pupin coils.

A multiple coil magnet is an electromagnet that has several coils of wire connected in parallel.

A Maxwell coil is a device for producing almost a constant magnetic field.

A Oudin coil is a disruptive discharge coil.

The polyphase coils are connected together in a polyphase system such as a generator or motor.

A relay coil is the copper winding part of a relay that produces a magnetic field that actuates the mechanism.

A Repeating coil is a voice-frequency transformer.

A Rogowski coil is an electrical device for méasuring alternating current.

A single coil is a type of pickup for the electric guitar.

A solenoid is a mechanical device, based around a coil of wire, that converts energy into linéar motion.

A Tesla coil is category of disruptive discharge coils, usually denoting a resonant transformer that generates very high voltages at radio frequencies.

A voice coil which is mounted to the moving cone of a loudspeaker.

A coilgun is a type of cannon that uses a series of electromagnetic coils to accelerate a magnetic shell to very high velocities.
