Abstract
The invention relates to an electromagnet for moving iron objects. It is formed with opposing magnetic heads (M.sub.1, M.sub.2), mounted at the ends of a carrying shaft (1), to which is also attached a steel cable (9). The electromagnet (M.sub.1, M.sub.2) can be raised and lowered with the help of the cable (9). By the magnetic heads (M.sub.1, M.sub.2) being attached to the shaft (1) by ball joints, a vertical line from a suspension point in a suspension means for the cable (9) carrying the electromagnet passes practically straight through the center of gravity for the magnetic heads and the iron object to be lifted. A very safe lift is therefore obtained when lifting with the electromagnet.
