A paramagnetic sample shows a net magnetisation of 8 Am^–1 when placed in an external magnetic field
A paramagnetic sample shows a net magnetisation of 8 Am–1 when placed in an external magnetic field of 0.6T at a temperature of 4K. When the same sample is placed in an external magnetic field of 0.2 T at a temperature of 16K, the magnetisation will be
(a) 32/3 Am-1
(b) 2/3 Am-1
(c) 6 Am-1
(d) 2.4 Am-1
