The influence of the tape-core layer number of fluxgate sensor to the demagnetization factor
This paper explains the influence of the tape-core layer number to the demagnetization factor of a fluxgate sensor. The demagnetization factor was calculated based on the physical dimension, the self-inductance of coil without inserting the core (Lno_core) and by inserting the core (Lcore) of the sensor. The calculated demagnetization factor to pick-up coil configurations of 2×80 are proportional, 0.51, 0.82, 1.15, and 1.40}10−3 whereas the one to pick-up coil configurations of 2}20 are 1.02, 1.58, 2.23, and 2.78}10−3, each of which uses the tape-core layer number 1,2, 3, and 4 respectively.
