Magnetic anisotropy as shown by hysteresis loops of tape-wound toroidal cores has been inspected as to the specific response of the anisotropy to core-internal forces during and after annealing. The loops of toroids are compared to that of strip samples annealed together in various ambience. The core-internal forces were manipulated by means of different core construction, too. The results show that it is the heterogeneity, which produces the most effective forces. Different annealing-induced ribbon shrinkage makes the cores effectively heterogeneous and governs their magnetic response, whereas inherent ribbon heterogeneity affects the core properties, too, and is essential for homogeneous cores.
