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

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
