It is a device that uses an electromagnet on one circuit to switch on anther circuit.
A
Actuator
B
Electromagnet
C
Magnetic Relay
D
Metallic Port
Explanation: 

Detailed explanation-1: -Relays are electromechanical devices that use an electromagnet to operate a pair of movable contacts from an open position to a closed position.

Detailed explanation-2: -An electromagnetic relay is an electrically operated switch that is used to control a circuit by an electromagnetic mechanism. It consists of a coil of wire, a movable armature, and one or more sets of contacts.

Detailed explanation-3: -In this case you would use a switching transistor. A transistor is an electronic device that can work as a switch. It allows control of a large current by a smaller current as does a relay. Unlike a relay, however, a transistor is not mechanical, and can operate much faster than a relay.
