MAGNETIC TRANSDUCER ASSEMBLY WITH WINDINGS POSITIONED SO AS TO PICK UP LEAKAGE FLUX

摘要

A magnetic transducer defining a substantially closed magnetic circuit including a pair of core halves separated by a front non-magnetic gap and defining an internal aperture having a diverging side wall portion extending from the rear of the front gap. A head winding is disposed about the core half and through the aperture and encompasses the core half so that there is no magnetic shunt across the winding. The turns of the winding closer to the front gap are disposed adjacent the front gap on the diverging side wall portion and in the path of the principal concentration of flux at the back of the front gap so as to significantly reduce the amount of flux which does not link the winding.
