を打ち消す方法が知られていた。Conventionally, in order to reduce the irregular magnetic field at the lead-out part or the transition part between turns of an electromagnetic wire ring, the dimensions of the conductor are locally changed and the lead-out part or the transition part between turns are overlapped to narrow the irregular current region. As described in Japanese Unexamined Patent Publication No. 62-140403, a structure has been known in which the protruding parts cross each other on the outside of the protruding parts to cancel out the misaligned magnetic fields. Alternatively, as described in Japanese Unexamined Patent Publication No. 61-256278, a method has been known in which an auxiliary coil is added near the irregular current region of the main coil to cancel out the irregular magnetic field.

という問題があった。In the conventional technology, in order to locally change the conductor dimensions and overlap the lead parts or the inter-turn transition parts, the current concentrates at the place where the conductor dimensions change, and the number of welded parts of the conductor increases. This has the problem of lowering reliability and making manufacturing difficult.

いう問題があった。In addition, when the lead parts are crossed on the outside of the lead part to cancel out the irregular magnetic fields, the coil becomes multi-stage.
When the irregular magnetic field created by the lead-out part or the inter-turn transition part becomes large, the lead-out lines need to intersect greatly.
There is a problem in that the leading portion widely spreads outward, and as a result, the irregular magnetic field cannot be sufficiently canceled near the leading portion.

あった。On the other hand, if an auxiliary coil is provided to cancel the irregular magnetic field, a separate type of flow is required, and the current flowing through the auxiliary coil must be controlled in accordance with the current flowing through the main coil, making the system complicated. Therefore, there were problems in that it became more expensive and the reliability of the system decreased.

。According to the present invention, the lead-out portion, the inter-turn transition portion, the lead-out unwinding wire, and the lead-out crossover wire are connected in series, and the same current flows through them. Therefore, even if the current value changes, the irregular magnetic field created by the lead-out part and the transition part between turns, and the magnetic field created by the lead-out unwinding wire and lead-out crossover wire will change in unison, so no external adjustments should be made. The irregular magnetic fields cancel each other out without any problem, and the total irregular magnetic field becomes sufficiently small.

できる。When the lead portion 2 is taken out above the coil, an irregular current region A is generated by the transition portion 3 between the outermost turns. Therefore, the output crossover wire 4 from the output section 2b to the output section 2C is arranged on the inner diameter side so as to surround the inter-turn transition section.The magnetic field generated by the output crossover wire 4 is generated by the outermost turn inter-turn transition section 3. Since the irregular magnetic field is canceled, the irregular magnetic field can be reduced.
口出し渡り線４の囲む面積は、自由に定める事ができる
