Abstract: A magnetic body inspection method and magnetic body inspection apparatus (1) that has a magnet (10) and a magnetic sensor (20) that outputs electric signals. At least two electric signals are obtained by the magnetic sensor (20). A magnetic body present inside a nonmagnetic body can be detected non-destructively, by outputting the difference between the two obtained electric signals.
