In response to the alternating current input from 1, an alternating current change in magnetic flux as shown in FIG. 2 occurs. At this time, since the core 3 forms a closed magnetic circuit, almost no magnetic flux leaks out. Then, the magnetic flux also changes in an alternating current manner in the part where the secondary coil /l/2 is wound.If 3 degrees, then according to MAXWELL's equation, the secondary coil /l/2 has primary and secondary coils. UE'=L pressure is generated depending on the winding ratio.
