It's an electrical magnetic valve, when you apply electrical power to the magnet, it allows a rod to move, opening up the fuel supply, to let the engine start.
Solenoid: a coil of wire usually in cylindrical form that when carrying a current acts like a magnet so that a movable core is drawn into the coil when a current flows and that is used especially as a switch or control for a mechanical device (as a valve)
I solenoid, is a relay. Sometimes it's on the starter motor, sometimes it's on the body of the car, some ware under the hood. It allows a low voltage switch, such as an ignition key, to start a hi voltage device. When you turn the key, it completes a current to the solenoid. The solenoid then switches on a 12v hi amperage switch to the starter.
All a solenoid really is, is an electro magnetic switch. The locks on your car work the same way.
