360443 A paramagnetic sample shows a net magnetisation of \(6\,A{m^{ - 1}}\), when placed in an external magnetic-field of \(0.4\;T\) at a temperature of \(3\;K\). When the same sample is placed in an external magnetic field of \(0.6\;T\) at a temperature of \(20\;K\), the magnetisation will be

1 \(2.3\,A/m\)
2 \(5.62\,A/m\)
3 \(3.68\,A/m\)
4 \(1.35\,A/m\)
