Patent ID: 6989730

Claim:
A permanent magnet, comprising: a body having a body axis and comprising a plurality of discreet components, each component being in the shape of a disk and having a generally rectangular shape in cross section and each component being radially spaced from the body axis and also being disposed approximately an equal distance from the body axis and, further, each component being circumferentially spaced an approximately equal distance such that between at least a portion of each component is a space that is generally trapezoidal in cross section, and wherein each of the components comprise a cavity and a component axis, and wherein each of the components further comprise: an inner ring comprising a magnetic substance and being rotatable about the component axis, the inner ring comprising a plurality of inner segments each having an inner segment magnetic field; and an outer ring also comprising a magnetic substance and being rotatable about the component axis, the outer ring comprising a plurality of outer segments each having an outer segment magnetic field and the outer ring being located in proximity to the inner ring whereby each of the inner segment magnetic fields and the outer segment magnetic fields interact; wherein each of the components are interconnected together via a moldable plastic substance.
