A magnetic phonograph pickup comprises interfitting stylus and sensing assemblies. The stylus is connected to a ferromagnetic element which is magnetically saturated by at least a pair of permanent magnets which are arranged, in a common plane at right angles to the plane of symmetry through the stylus assembly, adjacent this element with similar poles directed toward it. The sensing arrangement comprises coils adjacent the element which sense its movement and produce an output signal. The entire pickup is symmetrical about a central plane of symmetry, and the magnets are inclined to this plane. |
