ABSTRACT:
Shearing motion between first and second parts of an electromagnetic lock for maintaining a door shut are translated into a force tending to lift the second part away from the first part of the energized lock, and the shearing motion is countered by countering the latter force with the magnetic attraction between the first and second parts of the energized electromagnetic lock. The mechanical friction between the mutually attracted first and second lock parts is added to the full holding force between these parts, so that the holding power of the lock considerably exceeds the holding power generated by the magnetic field between the first and second parts alone.
