Abstract

A complex magnetic field generating device, comprising a frame, a plurality of magnets capable of producing a magnetic field, wherein each of the plurality of magnets has a north pole and a south pole and a longitudinal axis passing therethrough, the plurality of magnets are positioned in a side by side axis parallel orientation and are partially held in place by the frame, a coil of electrically conducting material wrapped about the plurality of magnets and orthogonal to the longitudinal axis of each of the plurality of magnets, and a source of electrical energy for supplying an electrical current to the coil enabling a magnetic field detectable with iron filings to be produced therefrom. A switch is provided to enable the electrical current to flow in a first direction and a second direction opposite to the first direction. The plurality of magnets that are positioned in a side by side axis parallel orientation are oriented so that the like poles of the plurality of magnets are positioned adjacent each other.
