A permanent magnet assembly, for engaging a generally planar surface of a ferromagnetic object to affix items of interest thereto, includes a shell of a magnetic material. The shell has a portion of either a magic sphere or a magic cylinder and a cavity and the shell terminates in a surface that is generally planar for engaging a ferromagnetic object. The permanent magnet assembly also has an insert located in the cavity. A method of fabricating the permanent magnet assembly is also presented.
