In engineering, a solenoid is a device that converts electrical energy to mechanical energy, using an electromagnet formed from a coil of wire. The device creates a magnetic field [ 1 ] from electric current , and uses the magnetic field to create linear motion.

An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix). [ 1 ] [ 2 ] 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 ...
A solenoid (/ ˈ s oʊ l ə n ɔɪ d / [1]) is a type of electromagnet formed by a helical coil of wire whose length is substantially greater than its diameter, [2] which generates a controlled magnetic field. The coil can produce a uniform magnetic field in a volume of space when an electric current is passed through it.
Here the energy is stored by disconnecting the coil from the larger system and then using electromagnetic induction from the magnet to induce a current in the superconducting coil. This coil then preserves the current until the coil is reconnected to the larger system, after which the coil partly or fully discharges. Refrigeration system
Non-magnetic core tubes are used to isolate the fluid from the coil. The core tube encloses the plugnut, the core spring, and the core. The coil slips over the core tube; a retaining clip engages the depression near the closed end of the core tube and holds the coil on the core tube. Solenoid valve designs have many variations and challenges.
A starter solenoid is an electromagnet which is actuated to engage the starter motor of an internal combustion engine. It is normally attached directly to the starter motor which it controls. Its primary function is as the actuating coil of a contactor (a relay designed for large electric currents) which connects the battery to the starter ...
Often involving electromagnetic principles such as in relays, which allow a voltage or current to control another, usually isolated circuit voltage or current by mechanically switching sets of contacts, and solenoids, by which a voltage can actuate a moving linkage as in solenoid valves.
