A sample of paramagnetic material is placed in an external magnetic field to get magnetized. Intensity of external magnetic field is slowly increased to a value that magnetization in sample of material becomes constant. Now temperature of this magnetized sample is decreased. What will be the effect on magnetization of sample due to decrease in temperature?

Answer»

Magnetization will INCREASE
Magnetization will decrease
Magnetization REMAINS unaffected
Magnetization may increase or decrease

Solution :On decreasing the temperature, alignment of atomic MAGNETS is not disturbed and HENCE sample maintains the intensity of magnetization.
