Abstract (en)
The electrically conducting, magnetic powder (1) contains or consists of electrically conducting and magnetic particles (2). The particles can be pre-magnetized so as to attract each other. The particles have a mean grain size that is smaller than 50 microns or smaller 40 microns or smaller than 30 microns. The particles are essentially spherical. Independent claims are also included for the following: (a) an electrically conducting, magnetic liquid; and (b) an electrical part, especially a switch or potentiometer.
Abstract (de)
Die vorliegende Erfindung betrifft ein Pulver (1) mit elektrisch leitenden und magnetischen Partikeln (2). Ein elektrisch leitendes, magnetisches Pulver (1) kann beispielsweise in einem elektrischen Bauteil, insbesondere in einem Potentiometer, zur Übertragung eines elektrischen Signals und/oder einer elektrischen Spannung und/oder eines elektrischen Stroms zwischen wenigstens zwei elektrischen Kontakten dienen. <IMAGE>
