Question

Assertion : Susceptibility is defined as the ratio of intensity of magnetisation $I$ to magnetic intensity $H$.
Reason : Greater the value of susceptibility smaller the value of intensity of magnetisation $I$.

• 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)

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.
