ABSTRACT:
A magnetically operated lock includes a fixed lock body in which a plurality of fixed permanent magnets are disposed in a predetermined pattern. Aligned with each permanent magnet is a hole in which a movable magnet is slidably disposed, the movable magnet being oriented to be repelled by the fixed magnet. A lock shaft is pivotally secured through the lock body, and a rotor secured to the shaft is disposed adjacent to the openings of the holes receiving the movable magnets. The rotor includes a plurality of detents which receive the movable magnets, locking the shaft in a fixed position. The key comprises a disc having a plurality of magnets embedded therein and oriented to repel the movable magnets and free the rotor and shaft for rotation.
