Claim:
1. An electrical device comprising: an electrode arrangement comprising a magnet and an electrode, an electrically conducting movable device, movable relative to the electrode arrangement and spaced apart from the electrode arrangement, whereby a gap is formed therebetween, and a suspension comprising a liquid, a plurality of magnetic particles dispersed in the liquid and a plurality of non-magnetic electrically conducting particles dispersed in the liquid, which non-magnetic electrically conducting particles have higher electric conductivity than the magnetic particles, wherein the suspension extends between the electrically movable device and the electrode arrangement in the gap, and wherein the magnet is arranged to provide a magnetic field through the suspension to thereby align the non-magnetic electrically conducting particles between the electrode arrangement and the electrically conducting movable device to obtain an electrical connection between the electrode arrangement and the electrically conducting movable device.
