Abstract
The apparatus seeks to improve the performance of audio, video and other electronic equipment 2 by applying an external magnetic field 7 across the equipment with the aim of improving the equipments performance. The field may be sufficiently strong to swamp residual magnetism in components 5, 6 of the equipment 2 that may exist and may help to align all magnetic domains in the same direction. At least two permanent magnets 3 or electromagnets with opposite poles facing Further one or more bodies 8 of a material of high electrical conductivity may also absorbed or dissipate current generated fields. The magnets may arrange the field to be vertical or horizontal (fig 3). One embodiment uses substantially planar assemblies which may comprise a single permanent magnet 3 or an array and may also use magnetic materials 13 of various shapes (figs 4,5 9 to 14) to spread and widen the magnetic field. An alternative arrangement is shown in figure 6 where the magnetic assemblies are provided at a localised position inside the equipment housing. Further embodiments instead use electro-magnets which may be driven with DC current or AC current at preferably above 50kHz. The idea may also be applicable to directing a magnetic field across wires or cables as figures 11 and 12 show. Other equipment that may be used with the invention include a projector (fig 13) and satellite receiver LNB (fig 14).
