PURPOSE:To raise the permeability and to attain a high saturating magnetic flux density with small magnetomotive force by a method wherein a magnetic pole, a lead and a yoke are formed with a noncrystalline material. CONSTITUTION:A bobbin 3 is provided at a base 2, a coil 4 is wound around the bobbin 3, the bobbin 3 is supported by the magnetic pole 5, a permanent magnet 6 is placed between the magnetic poles 5 and 5, the lead 8 is provided and covered by the yoke 10 and the electromagnetic mechanism is formed. Among the magnetic pole 5, the lead 8 and the yoke 10 of said electromagnetic mechanism, one or more of which are formed by a noncrystalline material. As the noncrystalline material has a high permeability, a high saturating magnetic flux density can be attained with small magnetomotive force by performing the procedures above-mentioned. |
