    A paramagnetic substance is placed in a weak magnetic field and its absolute temperature T is increased. As a result, its magnetization

    A)  increases in proportion to T

    B)  decreases in proportion to \[\frac{1}{T}\]

    C)  increases in proportion to\[{{T}^{2}}\]

    D)  decreases in proportion to \[\frac{1}{{{T}^{2}}}\]

    Correct Answer: B

    Solution :

    The magnetization \[I\propto \frac{1}{T}\] As temperature is increased the magnetization decreases,
