Method and apparatus for the reduction of the intensity of magnetic field emissions from display devices and other magnetic field emitters comprising an active magnetic field bucking system and a passive magnetic shield, for use either singularly or in combination. Various circuits are disclosed for generating a bucking current necessary to buck the emitted magnetic field. The magnetic shield comprises a material selected from the group consisting of manganese or aluminum doped yttrium aluminum or yttrium iron garnet, iron doped glass, iron based thin films, ferrous fluoride, ferrous borate, and combinations thereof.
