A motor includes a stator and a rotor. The rotor is relative to the stator, and has a rotation axis. A magnet and a magnetic-material member magnetically interact with each other. The magnet and the magnetic-material member are provided for enabling the stator and the rotor to magnetically attracting each other. The magnet has a shape of a ring, and is coaxial with the rotation axis. The magnet has an inner circumference and an outer circumference. The inner circumference and an outer circumference have a common center. The magnet has a plurality of N and S poles alternately arranged along a circumferential direction thereof. At least one of boundaries between the N and S poles extends on a straight line out of the common center. A method of manufacturing the motor, and a method of magnetizing a raw member for the magnet are also disclosed.
