Abstract
A pair of first measurement coils is disposed so as to sandwich magnetic particles. A pair of second measurement coils is disposed so as to sandwich magnetic particles and the pair of first measurement coils. A pair of alternate-current magnetic field application coils is disposed so as to sandwich magnetic particles, the pair of first measurement coils, and the pair of second measurement coils. A measurement device outputs a signal representing a difference between a signal measured by the pair of first measurement coils and a signal measured by the pair of second measurement coils.
