Abstract
Abstract An electrical magnet having a support structure which comprises a flat plate of structural material and abutment means engaging the conductor of the electrical magnet to the plate. The abutment means may comprise a groove in a face of the plate which receives and restrains the conductor, a raised flange on a face of the plate which forms such a groove, or a flange which extends around and is affixed to the periphery of the plate and which is formed to fit tightly over a coiled conductor. When current is flowing in the conductor of the magnet, all points on the conductor will experience a magnetically induced force, one component of which is in an outward direction parallel to the plane of the plate. The abutment means opposes this component of the force and transmits it to the plate, which is consequently stressed in tension in two dimensions. Several individual magnets supported by the support structure may be combined to form large magnets having solenoidal, toroidal or other configurations. The magnets may be built with a normal or a superconducting electrical conductor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
An electrical magnet, comprising: a. a coil of composite conductor formed of a superconducting material and a normal conducting material and having an outer periphery; b. a substantially flat plate having two opposite substantially parallel faces and a periphery substantially conforming to the outer periphery of said coil; c. a flange affixed to and extending around the periphery of said plate, said flange fitting over and restrainably engaging the outer periphery of said coil with said coil lying in a plane substantially parallel to the faces of said plate, whereby electrical current passing through said composite conductor, when it is maintained at temperatures at which it is superconducting, will cause said coil to exert outward forces parallel to the faces of said plate on said flange, with said flange transmitting such forces to said plate whereby said plate is stressed in two dimensions; and d. said plate and said flange thereon being formed of a structural material capable of carrying such forces exerted by said coil when said composite conductor is maintained at temperatures at which it is superconducting.
Claim 2
Dependent Claim
179 words
An electrical magnet, comprising: a. a coil of composite conductor formed of a superconducting material and a normal conducting material and having an outer periphery; b. a substantially flat plate having two opposite substantially parallel faces and a periphery substantially conforming to the outer periphery of said coil; c. a flange affixed to and extending around the periphery of said plate, said flange fitting over and restrainably engaging the outer periphery of said coil with said coil lying in a plane substantially parallel to the faces of said plate, whereby electrical current passing through said composite conductor, when it is maintained at temperatures at which it is superconducting, will cause said coil to exert outward forces parallel to the faces of said plate on said flange, with said flange transmitting such forces to said plate whereby said plate is stressed in two dimensions; and d. said plate and said flange thereon being formed of a structural material capable of carrying such forces exerted by said coil when said composite conductor is maintained at temperatures at which it is superconducting.
Claim 3
Dependent Claim
29 words
The electrical magnet as specified in claim 1 wherein said flange is formed continuously with said plate, and said flange and plate are formed of a non-magnetic structural material.
Claim 4
Dependent Claim
31 words
The electrical magnet as specified in claim 1 wherein the composite conductor of said coil is stressed in compression by said flange when no electrical current is conducted by said conductor.
Claim 5
Dependent Claim
161 words
An electrical magnet, comprising: a. a substantially flat plate having two opposite substantially parallel faces and a periphery: b. a flange affixed to and extending around the periphery of said plate; c. a composite conductor formed of a superconducting material and a normal conducting material which is wound around the outside of said flange to form electrical magnet turns; d. means for securing said composite conductor to said flange, whereby electrical current passing through said composite conductor when it is maintained at temperatures at which it is superconducting will cause said composite conductor to exert outward forces parallel to the faces of said plate on said flange, with said flange transmitting such forces to said plate whereby said plate is stressed in two dimensions; and e. said plate and said flange thereon being formed of a structural material capable of carrying such forces exerted by said composite conductor when said composite conductor is maintained at temperatures at which it is superconducting.
