A paramagnetic material had a magnetic field intensity of 10^4 A/m. If the susceptibility of the material at room temperature is 3.7×10^-3, calculate the magnetisation.
(a) 37A/m
(b) 3.7A/m
(c) 370A/m
(d) 0
This question was addressed to me in unit test.
Question is from Theory of Ferromagnetism topic in chapter Magnetic Properties of Materials of Engineering Physics II
