Question

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

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

Answer 1

Answer: (C)

From the relation, susceptibility of the material
$\chi_{m}=\frac{I}{H}$
$\Rightarrow \chi_{m} \propto I$
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.
