ABSTRACT:
The disclosed strong magnetic field generator has a number of concentric conductor cylinders, each of which has a longitudinal slit so as to have an open sidewall. Exciting coils are mounted on the cylinders to induce an eddy current in each cylinder in a circumferential direction. A conductor plate with a central hole and a radial slit extending from the central hole to an open end at its periphery is connected to the concentric cylinders while placing the central hole at the center of all the cylinders and while aligning the longitudinal slits of all the cylinders with each other along the radial slit. Thus, the path of eddy current in each cylinder is closed through sidewall portions of the radial slit and the central hole, and the eddy currents of all the cylinders are superposed at the sidewall portion of the central hole for generating a very strong magnetic field there.
