The magnetisation process of magnetic materials is extremely important due to the potential applications of these materials. During the magnetisation process, a delay in the increase in magnetisation is observed when the magnetic field strength increases. This behaviour may be explained by the magnetic anisotropy of the studied material. The paper presents the results of research on primary magnetisation curves for magnetic alloys that exhibit soft-magnetic properties. The tested alloys are the so-called amorphous materials in which determining the preferred direction of magnetisation is difficult due to their structure. However, as our research indicates, it is in fact possible to distinguish directions of relatively easy and difficult magnetisation in amorphous materials, which implies that the phenomenon of magnetic anisotropy occurs in them.
