ABSTRACT:
Solenoid coils are provided that produce relatively low irradiation of electromagnetic fields with intense fields internally thereof for purposes of heating a metallic element, preferably a ferromagnetic element having a Curie temperature selected for the purpose for which the coil structure is to be employed, the coil structure in one embodiment comprising two coaxial coils of substantially equal diameter interconnected to produce in response to an alternating current being applied thereto out of phase magnetic fields that do not substantially interfere with one another as a result of the spacing between the coils. In a second embodiment the two coils are located between two additional coils that buck axial fields thereby together with fall off of the fields as the cube of the distance from the main coils provide a structure with low external radiation. The method of forming the first coil structure includes winding a pancake coil in the form of a spiral, rotating out of the plane of the coil the innermost leg of the spiral to provide the desired spacing of the coils, forming the pancake into a cylindrical shape with the cross members of the pancake being laid one over the other to provide cancellation of the fields produced by these members.
