Jiles-atherton theory
WebThe hysteresis loop of the core material in a test current transformer is simulated using the Jiles-Atherton theory. Comparisons are made between recorded and simulated waveforms and it is found necessary to replace the modified Langevin function used by Jiles and Atherton. Using an alternative function described in the paper, good agreement is … WebLa rémanence ou magnétisation rémanente ou magnétisme résiduel est la magnétisation laissée dans un matériau ferromagnétique (comme le fer ) après la suppression d'un champ magnétique externe. 1 Familièrement, lorsqu'un aimant est "magnétisé", il a une rémanence. 2 La rémanence des matériaux magnétiques fournit la mémoire ...
