Abstract
An assembly having a capsule containing a permanent magnet housed in a casing which is closed by a cover. The cover and the casing are both of ferromagnetic material. The bottom of the casing and the wall thereof are connected to each other by a narrow peripheral partition forming a saturable zone having high magnetic reluctance. The lines of flux developed by the magnet are thus concentrated through the base of the wall of the casing. The assembly is useful inter alia for the retention of dental prostheses.
