    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, and 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 system and method for motivating a particle, for example a drug molecule, to a predetermined location in three dimensional space by applying magnetic fields, which may be static or time-varying, to the particle. The magnetic fields may be applied by one or a plurality of magnets, and may be multipole of any order such as octopole or decapole. The electric current driving the magnet coils may be pulsed for inducing a voltage in the molecules to aid in motivation. In an exemplary embodiment of the invention in which the substance is a drug, for example a drug molecule or plurality of drug molecules, the magnets may be positioned outside the body of the person to be treated, and the magnetic field(s), which may be time-varying, are used to motivate the drug molecule(s) to a predetermined location in an animal's body. The animal may be a human.

    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.
