A magnetic lock is a type of lock that uses magnetic force to lock and unlock. Unlike traditional mechanical locks, magnetic locks typically do not require a mechanical key; instead, they are controlled by magnetic force. Magnetic locks can be divided into electromagnetic locks and pure magnetic locks. Electromagnetic locks require electricity to operate, while pure magnetic locks use the magnetic force of the magnetic material itself to lock and unlock.
Permanent Magnet Locks: These consist of strong permanent magnets such as neodymium iron boron and iron suction plates (or magnets with opposite magnetic poles). Relying on the principle of attraction between opposite magnetic poles, they automatically attract and lock when the door is closed. They require no electricity, are silent, and have no mechanical wear, making them commonly used in bedrooms, bathrooms, and other indoor spaces with low security requirements.
Electromagnetic locks (also known as magnetic locks): Based on the principle of electromagnetism, when energized, a coil winding around an iron core generates a strong magnetic field, attracting an armature plate to achieve locking; they open immediately upon power failure, meeting fire escape requirements, and are often used in access control systems, fire escape routes, and other locations requiring remote or power-off release.
