Question
Answer the following questions:
Why does a paramagnetic sample display greater magnetisation (for the same magnetising field) when cooled?
✓

Answer

Owing to therandorn thermal motion of rnolecules, the allqnments of dipoles get disrupted at high temperatures. on cooling, this disruption is reduced. Hence, a pararnaqnetlc sample displays greater magnetisation when cooled.
