PURPOSE:To enable the title magnetic field generating device to be made of a material hardly drawn out into wire by a method wherein an excellent conductor hardly drawn out into wire is buried in grooves cut in the surface of a body material. CONSTITUTION:A continuous groove 5a is cut in the surface of a body material to be a core 5 in electromagnets 1-3. The surface of the core 5 wherein the groove 5a is cut is insulation-processed and excellent conductor 6 for coil hardly drawn out into wire is contained in the groove 5a and a connecting part 5b. In this case, the conductor in liquid or solid state is buried in the groove 5a and the connecting part 5b. Later, the surface of the electromagnets 1-3 is coated with an insulator if necessary to be laminated into other electromagnet 4. |
