the law that the susceptibility of a paramagnetic substance is inversely proportional to the difference of its temperature and the Curie point and that the substance ceases to be paramagnetic below the Curie point.
the principle that the magnetic susceptibility of a paramagnetic substance is inversely proportional to the difference between its temperature and its Curie point
