Abstract :
Orthogonal fluxgate sensor was built using copper wire covered by electroplated permalloy. This type of sensor core has significant advantage over the sensors based on amorphous wires: it has no magnetic material in the central part, where the excitation field is low. 11 muV/nT sensitivity and less than 1 muT perming error were achieved for the first sensor prototype. The used core geometry also allows to measure both longitudinal and circumferencial hysteresis curves, which is important for further development
