Patent abstract
A magnetic detection coil made of a single wire is constructed of one of superconducting and metallic materials. Four second-order differential coils are arranged so that a geometric figure obtained by connecting the respective centers of the four differential coils can form a parallelogram. By providing intersections between the four second-order differential coils, the values of magnetic flux respectively penetrating the differential coils are differentiated in three different directions.
