Elimination of spurious signal due to misalignment of magnetic axes in a differential magnetic-modulation transducer: Part II. Experimental

摘要

The efficiency of compensation for spurious signals from a primary differential magnetic-modulation transducer (ferromagnetic probe) as a function of operating parameters of a compensating component is discussed. Given an appropriate choice of the material, length, shape, diameter, and location with respect to the magnetically sensitive element, one can reduce spurious signals from the magnetic-modulation transducer due to the transverse component of the earth magnetic field by a factor of 15 to 20.
