Aus eigener Erfahrung kann ich aber sagen, dass Alnico 5 nicht gleich Alnico 5 ist etc. - in dem Sinne, dass nicht nur entscheidend ist, wie stark der Magnet geladen wurde, sondern auch, wie die Materialzusammensetzung aussieht. Das "Warum?" kann ich aber nicht beantworten, das geht wohl schon in den Bereich der Quantenphysik...
