Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : Susceptibility is defined as the ratio of intensity of magnetisation $I$ to magnetic intensity $H$.

Reason (R) : Greater the value of susceptibility smaller the value of intensity of magnetisation $I$.

In the light of the above statements, choose the correct answer from the options given below

• A. If both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. If the Assertion and Reason are true but Reason is not correct explanation of Assertion
• C. If Assertion is true but, Reason is false
• D. If Assertion is false but, Reason is true

Answer 1

Answer: (C)

If Assertion is true but, Reason is false

Answer 2

From the relation susceptibility of the material is $\chi_{m}=\frac{I}{H} \Rightarrow \chi_{m} \propto I$ Thus, it is obvious that greater the value of susceptibility of a material greater will be the value of intensity of magnetisation i.e., more easily it can be magnetised.
