What is the movable portion of a relay called?

• A. Coil
• B. Contact
• C. Armature
• D. Diode

Answer: (C)

The movable portion of a relay is known as the armature. The armature is a mechanical component that moves in response to the magnetic field generated by the coil when electrical current is applied. When the coil is energized, it creates a magnetic force that attracts the armature, causing it to move and make contact with other components of the relay, such as the contacts. This movement allows the relay to open or close circuits, making it a critical part of the relay's function in controlling electrical devices. In contrast, the coil is the part of the relay that generates the magnetic field, and the contacts are the fixed terminals that make or break the electrical circuit. A diode, on the other hand, is a semiconductor device used to control the direction of current flow and does not play a role in the functionality of a relay's mechanical operation. Understanding the role of the armature provides essential knowledge about how relays operate in various electrical and electronic applications.
