![]() The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external time-varying magnetic field through the interior of the coil generates an EMF ( voltage) in the conductor.Ī current through any conductor creates a circular magnetic field around the conductor due to Ampere's law. Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, and sensor coils. ![]() The magnetic field lines ( green) of a current-carrying loop of wire pass through the center of the loop, concentrating the field thereĪn electromagnetic coil is an electrical conductor such as a wire in the shape of a coil ( spiral or helix).
