Effects of Core Characteristics on Detection Performances in Zero Flux Type Magnetic Sensor

To verify the lack of dependence of a proposed zero flux type magnetic sensor on the material and shape of the core used, the authors constructed sensors using amorphous and supermalloy ribbons, and studied the detection characteristics. Detection levels were found to be unaffected by the type of ribbon core used and by the core shape, and an accuracy to about 0.02% (5 kA/m full scale) was achieved.
