In the submitted paper the computer simulation of the fluxgate core operati
ng on the second harmonic principle is presented. The predicted values are
compared to the ones obtained, by using a virtual magnetometer or a convent
ional fluxgate feedback magnetometer with synchronous detection. The applie
d continuous magnetic field was in the range of utilisation for this type o
f sensors. (C) 2000 Elsevier Science S.A. All rights reserved.
