Question

A paramagnetic material is kept in a magnetic field. The field is increased till the magnetisation becomes constant. If the temperature is now decreased, the magnetisation
(a) will increase
(b) will decrease
(c) will remain constant
(d) may increase or decrease

Answer 1

Answer:

magnetisation is inversely proportional to the absolute temperature ,hence when temperature decreases the kinetikc energy of particles decreases and magnetisation increases.
