ABSTRACT:
Methods of manufacturing a magnetic device and a manufacturing tool employing the methods. One of the methods includes the steps of: (1) applying an adhesive between opposing end faces of first and second core-portions of a magnetic core of the magnetic device, (2) placing the first and second core-portions proximate a permanent magnet during a cure-time of the adhesive, the permanent magnet causing the first and second core-portions to be magnetically attracted to one another to fix the first core-portion relative to the second core-portion and (3) separating the permanent magnet from the first and second core-portions following expiration of the cure-time, the adhesive thereafter fixing the first core-portion relative to the second core-portion.
