ABSTRACT:
A magic compass that gives the illusion it defies the laws of nature, providing usage as an aid for locating the direction of prayer as well as a novel promotional device for companies, having a magnetized compass needle (16) which is attached via a linking means to a non-magnetic pointer (22). This linking means, which can be rigid (11) or non-rigid (29), allows the non-magnetic pointer (22) to be angularly displaced from the magnetized compass needle (16). This linkage also provides the means for the non-magnetic pointer (22) to rotate and pivot freely via the inertia of the magnetized needle (16). A partition (20) hides the magnetized needle (16) below, and simultaneously creates a compass face for the non-magnetic pointer above. The non-magnetic pointer (22) is designed and shaped to appear identical to a true magnetized compass needle (32).
