ABSTRACT OF THE DISCLOSURE An electromagnetic pickup for use in sensing the mechanical motion of strings includes a ferromagnetic housing of elongate, longitudinally recessed form in which a ferromagnetic core is received. The core includes a plurality of coplanar, spaced, finger-like projections directed at the walls of the recess. Both the walls of the recess and the finger-like projections of the core are permanently magnetized to a common magnetic polarity and thus will concentrate by magnetic repulsion the flux into the gaps between the projections. A coil wound around the core then senses the flux changes of these concentrated flux fields due to string motion.
