ABSTRACT:
A magnetic device having a housing with a front wall. A first magnet assembly includes a north and south pole and a second magnet assembly also includes a north and south pole. The magnet assemblies are pivotally mounted in the housing and pivotal between a first position in which the north pole of the first magnet assembly and the south pole of the second magnet assembly face each other and are positioned adjacent the front wall of the housing, and a second position in which the north pole of the first magnet assembly and the south pole of the second magnet assembly face each other and are retracted from the front wall. An actuator pivots the magnet assemblies between their first and second positions while a spring urges the magnet assemblies toward the second position.
