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.
A magnetic pole layout method for double-wing opposite-attraction soft magnet, comprising steps of:
A double-wing opposite-attraction soft magnet plate comprising a soft magnet slat having two foldable wings interconnected by a folding line, the two wings having opposite longitudinal multitrace reverse magnetic poles, whereby the wings can be oppositely folded to attract each other, near the folding line, the magnetic poles being both obliquely obviated by the width of one trace of the magnetic poles.
A magnetizing device for double-wing opposite-attraction soft magnet, comprising:
