Abstract

PURPOSE: To enable efficient working of small diameter tubes etc. by placing plural forming coils so that a part of each coil is positioned on the same plane, and combining them to form a closed curve in connection with each other.
CONSTITUTION: By combining coils 3, 3 coiled in a plane, working of a tube 4 which is much smaller in diameter than minimum allowable radius of curvature ϒ of an electric wire can be made. However, this is low in power efficiency. When this is made to a three-dimensional channel-shaped coil 5, magnetic fields M', M" caused by the current that flows BCDE and FDHA are reverse in direction and cancels each other and only a magnetic field M caused by the current that flows through AB, EF is obtained. Accordingly, when this is connected and brought into close contact as coils 6, 6 or 7, 7, the two coils come into contact on a common plane, and on that plane, a part of the two coils form a closed curve which is regarded as a square. When current is let flow in the direction of the arrow, a strong magnetic field of steep rise-up is formed in the closed curve.
