Abstract
A magnetic signal measuring apparatus includes a first magnetic field applying unit that applies a first magnetic field to magnetic substances when a measured substance is binding to the magnetic substances, a second magnetic field applying unit that applies a second magnetic field to the magnetic substances to which the first magnetic field has been applied, and a SQUID that measures a magnetic signal derived from the magnetic substances. The first magnetic field has an intensity of such a degree that the magnetic substances do not flocculate with each other and such a degree that directions of magnetic moments in the magnetic substances can be aligned with each other. The second magnetic field has an intensity of such a degree that the magnetic substances do not flocculate with each other and such a degree that a magnetic signal can be obtained from the magnetic substances.
