PURPOSE:To remarkably simplify the manufacturing work, by forming a coil in a plurality of insulation tubes and coating the coil with other insulator through leading out the leads from a part between insulation tubes. CONSTITUTION:A loop shape induction wire 14 is provided in insulation tubes 13 and 14 having the length less than a half the entire circumference of a demagnetizing coil, the induction wire 14 is turned with pulleys 15, 16, and the coil is formed by turning the electric wire 17 fixing one end at the induced wire 14 along it for required number of turns. Further, among the part exposed between tubes 12 and 13, leads 20 and 21 are produced at A and other exposed part B is coated with moved insulation tube 18 having large diameter. |
