CIRCULAR MAGNETIZATION MEASUREMENT IN SOFT FERROMAGNETIC MATERIALS

Ján Ziman - Barnabáš Zagyi

   Quasistatic circular magnetization measurement in soft ferromagnetic materials is discussed using a simple model. Experimental procedure for measurement of circular magnetization is proposed and demonstrated on the stress annealed amorphous CoFeSiB wire. It has been shown that circular magnetization reversal may be influenced by introducing the axial current flow. The experimental procedure proposed enables to study magnetic reversal of chosen part of the sample eliminating the direct influence of its ends.
