COMEDK · Physics · 20. Magnetic Properties of Matter
Which of the following statements is CORRECT:
A. Paramagnetic property is an intrinsic property of the material that arises due to the presence of completely filled electron shells and does NOT depend on temperature.
B. Diamagnetic materials move from a region of weak magnetic field to strong magnetic field
C. Diamagnetic materials have negative magnetic susceptibility which means that they oppose the applied magnetic field
D. Paramagnetic materials have negative magnetic susceptibility which means that they oppose the applied magnetic field
- A B
- B A
- C D
- D C
Answer & Solution
Correct Answer
(D) C
Step-by-step Solution
Detailed explanation
Paramagnetic materials possess unpaired electrons, which leads to their magnetic properties. This property is temperature-dependent, as described by Curie's Law, where susceptibility \(\chi \propto \dfrac{1}{T}\). Thus, statement A is incorrect. Diamagnetic materials are weakly…
