Solenoid
Magnetic Device
A solenoid is often used to control something by using magnetism generated by electric current.

To start the engine, the car's solenoid engages the starter motor.
Electromagnetism
Solenoids demonstrate electromagnetism by turning electrical power into a magnetic field.

When the button was pressed, the solenoid activated the lock.
Technical Context
The term 'solenoid' is technical and most common in discussions related to physics and mechanics.

During the experiment, we measured the strength of the magnetic field produced by the solenoid.
