A magnetism detection device capable of improving the ability to detect magnetic features of coins and reducing a change in outputs due to a change in transport positions of coins, a coin recognition device, and a method for detecting magnetism using the magnetism detection device. The magnetism detection device includes a transport path on which a coin is to be transported, detection coils arranged on at least one side of a transport surface of the transport path and along a direction crossing a transport direction of the coin, and a controller configured to detect a magnetic feature of the coin based on an output signal from at least one but not all of the detection coils.

Magnetism detection device, coin recognition device, and method for detecting magnetism using magnetism detection device

Provided is a magnetic detection device () having a simple configuration and being capable of stably detecting fine portions of a coin. The magnetic detection device () comprises an excitation coil (LX) that generates an alternating magnetic field in a transport path for transporting a coin in a first direction, and a plurality of detection coils (L, L) that are arranged at a predetermined pitch in a second direction and that output a detection signal based on an induction voltage caused by the alternating magnetic field. Each of the plurality of detection coils (L, L) outputs a detection signal on the basis of the induction voltage induced by the alternating magnetic field, which changes due to the coin being transported along the transportation path.
