A paramagnetic gas consists of atoms each with a dipole moment of \( 1.5 \times 10^{-23} \mathrm{~J} \mathrm{~T}^{-1} \). The temperature of the gas is \( 27^{\circ} \mathrm{C} \) and its number density (number of atoms per unit volume) is \( 2 \times 10^{26} \mathrm{~m}^{-3} \).
(i) What is the maximum magnetisation of the sample - possible, when it is placed in an external magnetic - field ? (ii) Do you think, the sample can achieve close - to maxi-mum magnetisation for a magnetic field of 3
