A solenoid consists of a steel plunger inside an electric coil which is wrapped around a tube. When the coil is energised a magnetic field is created, and this draws the plunger into the tube. When the coil is de-energised a spring pushes the plunger back out of the tube.
The plunger can be used to allow or prevent flow through of air or liquid through another tube or chamber. This combination is called a solenoid valve.
