The electromagnetic lock is only magnetised when a current flows, so if theres no current, its not magnetic

A sufficiently large current flowing in the coil of the electromagnet creates a strong magnetic flux which is aligned with and attracted to the permanent magnet's field. The electromagnet needs a power source and is attached to the door frame. The permanent magnet's is a flat plate fixed to the door.

Rather like placing the opposite poles of two permanent magnets end to end. When activated, the magnetic fields cause an attraction force between each other large enough to approximate that of a lock keeping the doors closed.
