<p>PURPOSE:To enable the inductance to be enlarged, by connecting a magnetic body in parallel to a conductor and unifying them in a wire rod. CONSTITUTION:An electromagnetic coil conductive wire 1, which is manufactured by connecting a conductor 2 in parallel to a magnetic body 3 and unifying them in a wire ord, is in the shape of a concentric circle having the surface of the magnetic body 3 consisting of a ferromagnetic body, and coated with the conductor 2 such as copper, silver or the like. To form such an electromagnetic coil conductive wire 1 in the shape of a concentric circle, the powdery magnetic body 3, for example, is put into the tubular conductor 2 to be molded into the wire rod by means of an extruding machine. The resulting electromagnetic coil conductive wire 1 is wound to form a hollow coil whereupon a magnetic coil having larger magnetic flux and a resultant great inductance can be manufactured because the conductor 2 and the magnetic body 3 are in close contact with each other.</p> |
