To provide a method for easily taking out a permanent magnet which is not easily taken out from between pole pieces in a conventional magnetizing device, as the dimension of the magnet is large and a wide magnetic field is needed for the magnetization of the magnet, and to provide a device for taking out the permanent magnet.

A magnetizing device is constituted in a structure that a magnetic field gradient can be formed between a pair of pole pieces by providing each inclination on the magnetic pole surfaces opposing to each other of the pole pieces. In this structure, a reverse magnetic field having a gradient is applied to a permanent magnet subsequent to the magnetization of the magnet, and the take-out of the magnet is facilitated utilizing the repulsive force of the magnet.
