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 magneti

Options

  1. AB
  2. BA
  3. CD
  4. DC

Correct answer

D. C

Step-by-step solution

Paramagnetic materials possess unpaired electrons, which leads to their magnetic properties. This property is temperature-dependent, as described by Curie's Law, where susceptibility 1 T . Thus, statement A is incorrect. Diamagnetic materials are weakly repelled by magnetic fields. Consequently, they move from a region of strong magnetic field to a region of weak magnetic field. Thus, statement B is incorrect. Diamagnetic materials exhibit negative magnetic susceptibility ( Paramagnetic materials have positive magn
