A solenoid is an electromechanical device that converts electrical energy into linear motion. It typically consists of a coil wound into a cylindrical shape, an iron core or plunger that moves in response to the magnetic field generated by the coil, and a spring that returns the plunger to its original position when the current is turned off.
| Component | Description |
|---|---|
| Coil | Wound copper wire that generates a magnetic field when current flows through it. |
| Plunger/Core | Moves in response to the magnetic field, often made of iron or steel. |
| Spring | Returns the plunger to its original position when the electrical current is turned off. |
| Function | Converts electrical energy into linear motion, used in various applications like valves and locks. |
