It is an electromagnet with a rod in it. When you apply power to the electromagnet it will move the rod which usually does something useful. For example actuating an electrical switch or a valve. It is a quite useful thing on machines as it allows you to control fairly big controls using electrical control signals which means you can easily automate the machines.
