Abstract (en)

A magnetizing device includes: an inner magnetic portion having a first magnet assembly, a second magnet assembly, a third magnet assembly, and a fourth magnet assembly which are combined to form a hollow region. The first magnet assembly and the second magnet assembly each include: two first-direction magnets, a magnetic direction of each of the first-direction magnets is away from the hollow region, the third magnet assembly and the fourth magnet assembly each include two second-direction magnets, and a magnetic direction of each of the second-direction magnets faces the hollow region. A magnetic barrier portion surrounds the inner magnetic portion and includes a plurality of third-direction magnets, each two of the third-direction magnets has a joint surface therebetween, a magnetic direction of each third-direction magnet faces the joint surface, and magnetic poles of each of the third-direction magnets are opposite to magnetic poles of an adjacent third-direction magnet.
