Abstract
An actuating magnet, particularly a direct current electromagnet, has a cylindrical magnetically permeable shell or cover made from a rectangular sheet of metal bent into a square cylinder, the edges of the sheet forming a gap. Pole plates on the ends of the shell have recesses on their edges to receive projections on the shell. The pole plates have recesses in the corners, leaving the corners uncovered to receive fastening screws.
