Given below are two statements:
Statement I: The diamagnetic property depends on temperature.
Statement II: The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetizing field.
In the light of given statement, choose the correct answer from the options given below:
Statement I: The diamagnetic property depends on temperature.
Statement II: The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetizing field.
In the light of given statement, choose the correct answer from the options given below:
- (A)Statement I is incorrect but Statement II is true✓ Correct
- (B)Both Statement I and Statement II are true.
- (C)Both Statement I and Statement II are false.
- (D)Statement I is correct but Statement II is false.
Answer: (A)
Solution
Statement I is incorrect: Diamagnetism is essentially temperature-independent because it arises from the orbital motion of electrons, which is not significantly affected by thermal energy. Statement II is correct: In diamagnetic materials, the induced magnetic dipole moment is always opposite to the applied magnetizing field, which is the defining characteristic of diamagnetism.
