Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion A paramagnetic sample displays greater magnetization (for the same magnetizing field) when cooled. Reason The magnetization does not depend on temperature.A) if both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
B) if both Assertion and Reason are true but the Reason is nor the correct explanation of the Assertion
C) if Assertion is true but Reason is false
D) if Assertion and Reason are false
Correct Answer: C
Solution :
A paramagnetic sample displays greater magnetisation when cooled, this is because at lower temperature, the tendency to disrupt the alignment of dipoles (due to magnetising field) decreases on account of reduced random thermal motion.
