PHXII05:MAGNETISM and MATTER

360481 A paramagnetic sample shows a net magnetization of \(8A{m^{ - 1}}\), when placed in an external magnetic field of 0.6\(T\) at a temperature of 4\(K\). When the same sample is placed in an external magnetic field of 0.2\(T\) at a temperature of 16\(K\). The magnetization will be

1 \(6A\;{m^{ - 1}}\)
2 \(2.4A\;{m^{ - 1}}\)
3 \(\frac{{32}}{3}A\;{m^{ - 1}}\)
4 \(\frac{2}{3}A\;{m^{ - 1}}\)
