A magnetizing apparatus comprising:
- a holding member that holds a rotor including a magnetic body;
- a coil member including
- a support plate that is thin plate-shaped, and
- a coil that is incorporated inside the support plate and wound along a plane of the support plate;
- and
- a coil fixing portion that is configured to arrange and fix the coil member around an outer peripheral portion of the rotor in a manner so that a direction of electric current at a portion of the coil closest to the magnetic body coincides with an axial direction of the rotor,
- wherein
- the coil member generates a concentric magnetic field in accordance with a right-hand rule around the coil and magnetizes the magnetic body with the concentric magnetic field.
