All electrified locks utilize what principle to lock and unlock a security portal?

Electrified locks primarily operate based on the principle of electromagnetism. This principle involves the interaction between electric currents and magnetic fields. When an electric current flows through a coil of wire in the lock mechanism, it generates a magnetic field that can either attract or repel a metallic component, effectively locking or unlocking the door.

For example, in an electromagnetic lock (often called a maglock), when power is supplied, the electromagnet holds the locking armature in place against the door frame, preventing the door from opening. When the current is cut off, the magnetic field disappears, allowing the door to be opened. This reliance on electromagnetism is a key factor in the functionality of electrified locks, as it enables remote locking and unlocking through access control systems.

In contrast, while options like magnetism, static electricity, and mechanical force are related concepts, they do not fully encapsulate the operational mechanics of electrified locks. Magnetism often refers to the capability of materials to attract or repel based solely on magnetic fields without the electric current aspect. Static electricity involves charged particles but is not used for continuous locking mechanisms. Mechanical force pertains to physically engaging or disengaging locks, which is not the operational premise of electrified locks. Thus, electromagnet
