प्रश्न
Why does a paramagnetic sample display greater magnetisation (for the same magnetising field) when cooled?
उत्तर
Owing to the random thermal motion of the molecules, the alignments of dipoles get disrupted at high temperatures. On cooling, this disruption is reduced. Hence, a paramagnetic sample displays greater magnetisation when cooled.
