PROBLEM TO BE SOLVED: To maximize the magnetizing force, regarding an apparatus for magnetizing motors and a method of magnetizing motors. SOLUTION: An apparatus for magnetizing a motor includes a jig (2) for fixing a rotor part (1), and a pair of magnetizing units (5, 6) disposed around the rotor part (1). Elements to be magnetized (3) are arranged on the outer periphery part of the rotor part (1) in the circumferential direction. The number N of the elements to be magnetized (3) is an even number. The magnetizing units (5, 6) are magnetizing units, formed of an N-pole side magnetizing head (5), and an S-pole side magnetizing head (6). The N-pole side magnetizing head (5) and the S-pole side magnetizing head (6) magnetize the two elements to be magnetized, existing on one radial line. The magnetic flux, directed from the N-pole side magnetizing head (5) toward the S-pole side magnetizing head (6), is substantially a single straight line, has few curves, much fewer leakages of the effective magnetic flux as compared with that of the prior art, and has a magnetizing force strengthening effect.
