3) How Magnetic Locks Work ? Re: A magnetic lock, often referred to as a mag lock, consists of an electromagnet and an armature plate.
The magnet is mounted inside of the door opening, which prevents tampering, while the plate is installed on the face of the door.
When the magnet is connected to an electrical source, it produces a strong magnetic attraction that holds the magnet tight to the plate, effectively locking the door. The lock is typically powered using either the building's electrical system or a separate battery pack. Because a mag lock can only be used with DC power, a converter unit must be added when relying on building power. These locks are said to be "fail-safe," meaning that once the power goes out, the door will remain unlocked, allowing occupants to exit safely.
