Abstract
A single toroidal core is wound with excitation/detection windings for reciprocal-integral eddy current driving-detection means, the pick-up coil being wound around the circumference of the toroid core. The utilized fields being orthogonal for an inherent null. The preferred excitation is ramping sine-cosine currents generating a variable angular velocity driving dipole. A rotating field torus core having an excited poloidal winding for generating concentric n-s s-n diameter-wise dipoles on the plane of the torus for shifting the hemispherical sensing field eccentric in an orbital motion.
