Abstract

815,311. Magnetic structures. TESLA NARODNI PODNIK. Nov. 29, 1955 [Dec. 13, 1954], No. 34152/55. Class 38 (2). A permanent magnet is made from a mixture of ferromagnetic ferrite and a resilient binder such as natural or artificial rubber, or other suitable artificial material. Magnets may be cut from a sheet made by mixing ferrite powder of grain size less than 10Á with rubber in a calender. Their properties may be improved by application of a magnetic field.
