Abstract
The passive torsional flux characteristics of polar sensors as related to the effective flux length coupling the pick-up coil are elucidated. A sine-cosine excited toroidal driving core comprising stacked magnetic materials having different permeabilities for enhanced helical induction coupling to the pick-up core. Also an active torsional flux means utilizing stacked driving toroids concentrically coupled to the polar sensor pick-up core. Also, integral sensor/driver embodiment utilizing at least two stacked toroids.
