Vedclass · Answer

(A) According to Curie's Law,the magnetization $M$ of a paramagnetic material is directly proportional to the applied magnetic field $H$ and inversely proportional to the absolute temperature $T$. Mathematically,$M = C \cdot \frac{H}{T}$,where $C$ is the Curie constant. From this relation,we can see that for a fixed magnetic field $H$,the magnetization $M$ is inversely proportional to the temperature $T$ $(M \propto \frac{1}{T})$. This means that at a lower temperature,the material will show higher magnetization for the same applied field. Looking at the graph,for a constant value of $H$,the magnetization $M$ is highest for $T_1$ and lowest for $T_3$. Therefore,$T_1 < T_2 < T_3$.

The following graph shows the response of magnetization $M$ of a paramagnetic material to the applied magnetic field strength $H$ for three different temperatures $T_1$,$T_2$,and $T_3$. Which of the following is correct?
