Question

A  paramagnetic sample shown a net magnetisation of  $$8$$ $$A/m$$. When placed in an external magnetic field of $$0.6T$$ at a temperature of $$4K$$. When placed in an external magnetic field of  $$0.3T$$  at a $$16K$$ ,  then find magnetisation $$($$ in  $$A/m)$$ at this temperature

Infinity Learn · Accepted Answer

From Curie’s Law we can deduce a formula for the relation between magnetic field Induction, temperature and magnetisation                                                  I ∝BT⇒$$I2I1=B2B1$$×$$T1T2Put$$ $$I1=8A/m$$ , $$B1=0.6$$ , $$T1$$ $$=$$ $$4K$$ , $$B2=0.3TT2=16KI2=$$?∴$$I28=0.30.6$$×$$416$$⇒$$I2=1A/m$$
