ABSTRACT OF THE DISCLOSURE A mirror is held against a pointed supporting member by a magnetic field of attraction between a first magnetic assembly attached to the mirror and a second magnetic assembly spaced from the first assembly and directly or indirectly attached to the supporting member. The mirror can pivot in two directions in response to magnetic control fields produced by coils around the first magnetic assembly but is prevented by interlocking magnetic fields from rotating on an axis in a third direction. The interlocking fields may be produced by assymmetrically located magnetic members attached to the first and second magnetic assemblies or by dividing both the first and second magnetic assemblies into similar oppositely polarized sectors.
