PURPOSE:To provide a magnetic field detection coil which can specify the number and position of a plurality of current dipoles. CONSTITUTION:Three sets of four parallel grooves 11gamma-14gamma 11theta-14theta, and 11phi-11phi are made in the outer periphery of a bobbin 1 made of an cryogenic-resistant material with three orthogonal axes Bgamma, Btheta, Bphi as the centers. Supeconducting wires 2gamma, 2theta, 2phi are wound around for each axis in the order of +, -, -, +. |
