PURPOSE:To obtain a strong barrel magnetic field by permitting coils to cross with each other near a core neck part. CONSTITUTION:The neck part 1a of a core 1 is formed in concentrated winding, and a head part 1b in dispersion winding. And, since coils are allowed to cross with each other near the neck part 1a, forming a concentrated winding state also in this neighbourhood. Winding the coils in such a way causes a stronger barrel magnetic field to be formed at the neck part 1a and its neighbourhood with the same power as before, enabling wasteful use of power to be reduced. |
