The apparatus seeks to improve the performance of audio, video and other electronic equipment by effecting magnetic and electromagnetic interactions between components within such equipment. The field may be sufficient to swamp residual magnetism in components of the equipment that may exist. The apparatus comprises two magnet assemblies 17, 27 able to be arranged on opposite sides of the equipment 29 (vertically fig 1, or horizontally fig 2) and aligned, with north and south poles facing, so that a magnetic field 18 crosses through the components 19, 30 and PCB 20, 28 which may be inside the equipment (26). One embodiment uses substantially planar assemblies which may comprise a single permanent magnet or an array (figures 4, 5) of magnets (21, 24) and may also use magnetic materials (25). Various shapes of magnetic material (35, 39) and magnets (34, 38) are provided (see figures 8 to 10) that spread and widen the magnetic field from the magnets. An alternative arrangement is shown in figure 6 where the magnetic assemblies are provided inside the equipment housing and the field may be arranged to effect only some of the components inside. Further embodiments use electro-magnets (33) in the place of permanent magnets (see figure 7) which may be driven with DC current or AC current at preferably above 50kHz.
