Relays work on the principle of electromagnetic attraction and repulsion to control the flow of current in a circuit.

• Relays have an electromagnet which attracts an armature to make or break electrical contacts.

• When current flows through the coil of the relay, it creates a magnetic field that pulls the armature towards it, closing the contacts.

• When the current stops, the magnetic field disappears, and the spring returns...read more
