Patent ID: 7576454

Claim:
A dynamic magnet system comprising: a support structure to support a first and a second array of magnets, respectively, with a first support surface and a second support surface thereof, wherein each magnet in each array is disposed with a magnetic polarity opposite that of an immediately adjacent magnet in the same array and with a polarity identical to the magnet in the corresponding position in the other array, wherein each magnet has a first end and a second end and each magnet is disposed with magnetic axes substantially normal to the support surfaces and wherein the support structure is formed so that the first array is aligned and juxtaposed with the second array with the ends of the magnets of the first array separated from the corresponding ends of the magnets of the second array by a gap; at least one magnetic yoke comprising material with high magnetic permeability disposed to cover and magnetically link only the first ends of the magnets of at least one of the arrays leaving the second ends of the magnets substantially exposed in the gap; and a carrier sized and disposed to fit within the gap in proximity to the exposed second ends of the magnets, the carrier carrying a coil so that relative motion between the coil and the magnet ends substantially normal to the magnetic axes induces a flow of electrons within the coil.
