JEE Mains · Physics · STD 12 - 5. Magnetism and matter
Given below are two statements: Statement\(- I\) : Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature. Statement\(- II\): Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field. Choose the \(CORRECT\) answer from the options given below : -
- A Both statement\(- I\) and statement \(-II\) are true.
- B Both statement\(- I\) and Statement \(-II\) are false.
- C Statement\(- I\) is true but statement\(-II\) is false.
- D Statement\(-I\) is false but Statement\(-II\) is true.
Answer & Solution
Correct Answer
(A) Both statement\(- I\) and statement \(-II\) are true.
Step-by-step Solution
Detailed explanation
According to curie's law, magnetic susceptibility is inversely proportional to temperature for a fixed value of external magnetic field i.e. \(\chi=\frac{C}{T}\). The same is applicable for ferromagnet and the relation is given as…
