ABSTRACT:
An electromagnetic forming method is disclosed which effects desired forming on a given workpiece by disposing on the surface of the workpiece a driver obtained by superposing a highly electroconductive metal foil repeatedly over itself, opposing a primary coil to the driver, feeding electric current for forming to the primary coil thereby generating induced current in the driver, and allowing the workpiece to be formed by the resultant repulsive force exerted between the driver and the primary coil.
