The invention provides a magnet which may be formed using a rare earth material sich as neodymium-iron-borone. The cross section of the magnet is designed by first selecting an initial cross sectional shape having an area A and then removing from the initial cross-sectional shape a region having an area a to produce an intermediate cross- sectional shape. The interior of an angle is then removed from the intermediate cross- sectional shape having a vertex located in the region to produce the final cross-sectional shape. The invention also provides a device containing the magnet and a method for producing the magnet.
