What Does Solenoid Mean?

A solenoid is a coil of enameled or insulated wire in a corkscrew shape wrapped around a rod-shaped armature usually made of iron. A solenoid is an electromechanical device capable of producing a magnetic field and motion of the armature. Solenoids have wide applications which include use in automobile starters, switches, valves and inductors in electronic circuits.


Techopedia Explains Solenoid

The core material in a solenoid is of a ferromagnetic nature. As a result, a magnetic field in an activated solenoid has negative and positive poles, and can attract or repel materials which are sensitive to magnets. The electromagnetic field in a solenoid results in the armature moving forward or backward due to the solenoid coil. Solenoids are either used to generate a controlled magnetic field or act as a transducer device capable of producing linear motion. Solenoids are extremely helpful for numerous applications, including automated equipment.
