Given below are two statements; one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A:\) Electromagnets are made of soft iron. Reason \(R:\) Soft iron has high permeability and low retentivity. In the light of above, statements, choose the most appropriate answer from the options given below.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(B) Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\)
Step-by-step Solution
Detailed explanation
Electromagnets are made of soft iron because it has high permeability and low retentivity.
So, Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\)
