Which of the following is a type of electrical locking mechanism?

Magnetic locks are indeed a type of electrical locking mechanism. They operate using an electromagnet, which generates a magnetic field that holds the locking mechanism in place. This type of lock requires an electrical current to be fed to it in order to maintain its locking state; when the power is turned off, the magnetic force is removed and the door becomes unlocked.

Other types of locks mentioned, such as mechanical locks, combination locks, and deadbolts, operate primarily through physical mechanisms and do not rely on electrical power. Mechanical locks utilize internal gears and tumblers to secure a door, while combination locks use a series of dials or keys to unlock, and deadbolts are typically operated by rotating a key or thumb turn without requiring electricity. Thus, magnetic locks stand out as the only option that functions through an electrical system, highlighting their specific role in electronic access control systems.
