At its core, a solenoid is an electromechanical device that converts electrical energy into linear motion. It typically consists of a coil of wire wound around a cylindrical metal core. When an electric current passes through the coil, a magnetic field is generated, causing the metal core, or plunger, to move. This movement can be harnessed to perform various functions, such as opening valves, locking mechanisms, or even activating switches.
