Abstract: A system and method for a permanent magnet, having boron, iron, and a rare-earth material. The rare-earth material includes neodymium, at least 50 weight percent praseodymium, 0-20 weight percent terbium, and 5-25 weight percent dysprosium, wherein the permanent magnet comprises an intrinsic coercivity of at least 17 kilo Oersteds. Due to this high intrinsic coercivity, the permanent magnet may be subjected to high-temperature (e.g., greater than 80° C.) applications (e.g., as a component of a motor, generator, and so forth). In one exemplary application, a generator within a commercial wind turbine or windmill incorporates 3 tons of the permanent-magnet material.

Abstract: A method for fabricating a component includes providing a workpiece, an electroerosion apparatus comprising an electrode tool. The electroerosion apparatus is operated on the workpiece, for removing a portion thereof. A method for fabricating a composite magnet includes a workpiece comprising a composite material including a magnetizable material and an epoxy resin. An electroerosion apparatus, comprising an electrode tool having an abrasive material, removes a portion of the workpiece by an abrasive action of the electrode tool on the workpiece.

Abstract: A method of manufacturing a magnetic resonance imaging (MRI) device is provided including providing at least one magnet positioned between a keeper device and a yoke, the keeper device being positioned at a pole region of the at least one magnet, positioning at least one pole device at the pole region of the at least one magnet, and removing the keeper device from the pole region to allow the at least one pole device to be positioned at the pole region of the at least one magnet.

Abstract: A composition of matter suitable for use as a permanent magnet includes a rare earth-transition metal-boron alloy, where at least 30 weight percent of the rare earth content of the alloy comprises Pr, at least 50 weight percent of the transition metal content of the alloy comprises Fe, and the alloy contains less than 0.6 weight percent oxygen.
