AIIMS 2019 Physics Paramagnetism MCQ Question
Assertion: Paramagnetic substances get poorly attracted in magnetic field.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because paramagnetic substances are weakly attracted to magnetic fields due to the presence of unpaired electrons, which create a net magnetic moment. However, the reason provided is not a correct explanation of the assertion; paramagnetic materials are actually attracted to magnetic fields, albeit weakly, rather than being poorly attracted. Option A is incorrect because the reason does not explain the assertion, while options C and D are incorrect as they misrepresent the truth of the assertion and the reason. Understanding the behavior of paramagnetic substances is crucial in fields such as material science and chemistry, where magnetic properties play a significant role.
