Abstract:
1. A magnetic pole layout method for double-wing opposite-attraction soft magnet, comprising steps of: (a) preparing a magnetic conductive tray having multiple longitudinal guide channels and oblique guide channels for defining at least one pair of corresponding magnetizing regions; (b) sequentially winding a magnetizing conductor on the corresponding magnetizing regions along the longitudinal guide channels and the oblique guide channels; (c) horizontally placing a magnetizable soft plate on the magnetic conductive tray; (d) feeding a pulse power to form reverse magnetic poles on the corresponding magnetizing regions for simultaneously magnetizing the magnetizable soft plate; and (e) cutting the magnetized soft plate into elongated slat in the direction of the formed magnetic poles and then transversely folding the elongated slat about a section magnetized by the oblique guide channels to form the double-wing opposite-attraction soft magnet.
