ABSTRACT:
Disclosed is a coil device having feeders which are connected to a power source and which are adapted to supply electric current, a coil conductor section which is connected at both ends to these feeders and wound into a coil in a position adjacent to the feeders, and dents formed in at least one of the coil conductors of the coil conductor section at positions in the vicinity of the feeders in such a manner as to generate current loops which cancel the error magnetic field generated by the error magnetic field current loop of the feeders.
