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 (L no_core ) and by inserting the core (L core ) of th...

Description
Summary: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 (L no_core ) and by inserting the core (L core ) 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.
