A paramagnetic material is placed in a magnetic field. Consider the following statements : (A) If the magnetic field is increased, the magnetization is increased. (B) If the temperature is increased, the increased the magnetization is increased.

Options

A. Statement A is correct and statement B is incorrect
B. Statement A is incorrect and statement B is correct
C. Both the statements are correct
D. Both the statements are incorrect

Answer

A

Explanation

When external magnetic field is increased then due to increased torque on atomic magnets more alignment occurs and this increases intensity of magnetization. Hence statement A is correct. On the other hand temperature acts against alignment so when temperature of the sample is increased then due to randomization intensity of magnetization is decreased.
