ABSTRACT:
Magnetic elements having unique shapes. In one example, the magnetic element defines an outer peripheral profile and a center point, wherein the outer peripheral profile includes a substantially curviform section and a notch section. The notch section may be configured to radially extend to at least the center point. In another example, a substantially circular or oval-shaped magnetic element defines an outer periphery and a gap void having an open end facing the outer periphery so as to form a gap along the outer periphery. The magnetic element optionally may not include an annular void that is spatially isolated from the gap void.
