PROBLEM TO BE SOLVED: To solve the problem in which influence of the mutual coupling which is caused by induction of current in a coil cannot be reduced even when cutting the connection between the coil and a circuit using a switch for opening/closing the connection therebetween to reduce the influence of the mutual coupling between the coils, if the coil has a parasitic capacitance.SOLUTION: An array coil system comprises a plurality of arranged detection coils, and terminators of resistors. The influence of mutual coupling between the detection coils is reduced by connecting two terminals of each coil of the plurality of arranged detection coils to a ground or DC voltage via the terminator. |
