Abstract :
Summary form only given. The authors we have used as cores circular discs of a very thin soft magnetic material. These cores are magnetized by a rotating magnetic field high enough to saturate them. Thus, the magnetization processes are due to magnetization rotation and the only losses are due to macro-eddy currents. This kind of devices can also be used to measure the magnetic field in two perpendicular directions by using a single core and, in principle, the exciting field frequency can be greater than in conventional fluxgate magnetometers.
