Abstract: A new type of flux-gate element employing an ordinary toroidal core without air-gap has been developed. By using tape-wound or laminated nickel-iron-alloy ring cores " ID-OD (inside diameter ...

Fluxgate sensors are typically ring cores of a highly magnetically permeable alloy around which are wrapped two coil windings: the drive winding and the sense winding (as shown in the figure). Some ...
