    摘要： A jaw-like cylindrical tool for producing a strong electromagnetic field for causing a Curie point heater to be energized having a curved cross-section that brings the two edges of the jaw-like structure into contact. Closely spaced conductors lie along the inner surface of the structure transverse to its axis while widely spaced conductors lie transverse to said axis along the outer surface of the structure. The inner surface of the structure has a plurality of axially extending ferrite rods lying immediately adjacent the inner surface conductors. The inner and outer surface conductors are connected so that the currents flow in opposite directions, the outer conductors reducing electromagnetic radiation while the ferrites and inner conductor spacing produce a strong central magnetic field irrespective of the field created by the opposing field produced by the outer conductors. The tool may be manufactured by laying each ferrite rod longitudinally along the flat surface of a D-shaped mandrel with the rods lying side by side transversely. Conductors are wrapped transversely around the curved surface of the mandrel and over the ferrite rods. The rods and conductors are bonded to one another, removed from the mandrel and the resulting structure curved until the longitudinal edges of the structure are in contact with one another.
