Question

Identify the expression for Curie’s constant from the following.

(a) χm = C × T

(b) χm = C × 2T

(c) χm = \(\frac {C}{T}\)

(d) χm = \(\frac {C}{2T}\)

I have been asked this question at a job interview.

I'd like to ask this question from Permanent Magnets and Electromagnets in chapter Magnetism and Matter of Physics – Class 12

Answer 1

Correct option is (c) χm = \(\frac {C}{T}\)

Best explanation: Curie’s law in magnetism states that the magnetic susceptibility of paramagnetic materials is inversely proportional to its absolute temperature and it is given by:

χm = \(\frac {C}{T}\)
