Abstract: The present invention provides a method of manufacturing magnets, including magnets comprising coil windings which may be multiple meters in length. In an embodiment, the support structure comprises a cylinder in which machined grooves are formed to define the magnet conductor path. The segments may consist of a composite material or a metal in the shape of a cylinder, but which need not be manufactured from a single piece of material. Rather, the support structure may be formed in multiple connectable segments which, when connected together, form a completed wiring support structure. Each segment may be of sufficient length to support multiple individual coil turns in a helical configuration. When the segments are connected the helical configuration continues without interruption from connectable segment to connectable segment. The segmented wiring support structure of the invention may be applied to linear or curved magnet geometries.

Abstract: A method for manufacture of a conductor assembly. The assembly is of the type which, when conducting current, generates a magnetic field or in which, in the presence of a changing magnetic field, a voltage is induced. In an example embodiment one or more first coil rows are formed. The assembly has multiple coil rows about an axis with outer coil rows formed about inner coil rows. A determination is made of deviations from specifications associated with the formed one or more first coil rows. One or more deviations correspond to a magnitude of a multipole field component which departs from a field specification. Based on the deviations, one or more wiring patterns are generated for one or more second coil rows to be formed about the one or more first coil rows. The one or more second coil rows are formed in the assembly. The magnitude of each multipole field component that departs from the field specification is offset.

Abstract: A continuous method of manufacturing permanent magnets and the permanent magnets created thereby. A fine powder is created from a combination of magnetic metals. The powder (a metal alloy) is placed in a non-magnetic container of any desired shape which could be, for example, a tube. The metal alloy and tube are swaged while a magnetic field is applied. Once swaging is complete, the metal alloy and tube are sintered and then cooled. Instead of sintering, a bonding agent can mixed into the powder. Following cooling, the metal alloy is magnetized by placing it between poles of powerful electromagnets with the desired field direction. The process of the invention enables mass-produced, cost-effective PM products, which are more robust, easily assembled into products, enables new “wire like” shapes with arbitrary magnetization direction. The process enables mass production of permanent magnets of any desired cross section, produces permanent magnets continuously that may be cut to any length, and may, in an embodiment, result in directional magnets.

Abstract: A method for continuous manufacture of permanent magnets. A material sheet is formed into an open tube, having a lengthwise opening. Magnetic powder may be poured into the lengthwise opening on a continuous basis. The tube opening is then formed closed and sealed. The magnetic powder is magnetically pre-aligned by subjecting it to a first magnetic field. The tube containing the powder may be compressed into a desired shape, forming an elongated permanent magnet. After compression, the elongated magnet is magnetized by a second magnetic field in two-step process, wherein the elongated permanent magnet is subjected to a magnetic field from first magnetizing coil that is pulsed with a first electric current in a first direction, followed by a second magnetizing coil being pulsed with a second magnetizing electric current in a second direction. The elongated magnet may be formed into any arbitrary shape, such as a ring or coil.

Abstract: Systems and methods for removing plaque from blood vessels by applying constant or time varying magnetic or electrical fields. In one embodiment a system includes winding configurations positioned about a central axis along which a body region may be placed. Each winding configuration generates a magnetic field in a direction which passes through the body region. A first winding configuration generates a first magnetic field component perpendicular to a second magnetic field component generated by a second winding configuration. In a related method for removing a deposit of plaque from a position along a wall of a blood vessel a magnetic field is applied which has a net direction predominantly orthogonal to the direction of the flow of blood through the vessel.
