ABSTRACT:
A magnetic pole layout method and a magnetizing device for double-wing opposite-attraction soft magnet. A magnetizing conductor is wound on a magnetic conductive tray. A pulse power is fed to the magnetizing conductor to multiple pairs of corresponding first and second magnetizing regions. A magnetizable soft plate is placed on the magnetic conductive tray and magnetized at one time to form multiple pairs of reverse magnetic poles. The magnetized soft plate is then cut into elongated magnet slat in the direction of the formed magnetic poles and then the magnet slat is oppositely folded about a folding line to form a double-wing opposite-attraction soft magnet. The double-wing opposite-attraction soft magnet can ride on a page of a book or a paper along the folding line to clip the page and serve as a bookmark.
