NEETPhysicsElectromagnetic Induction
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : The mutual inductance of coil 1 with respect to coil 2 is the same as mutual inductance of coil 2 with respect to coil 1. Reason (R) : Mutual inductance between coils is independent of current passing through the coil In the light of the above statements, choose the most appropriate answer from th
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
Step-by-step solution
- Assertion (A) states that the mutual inductance of coil 1 with respect to coil 2 is the same as the mutual inductance of coil 2 with respect to coil 1 ( M₁₂ = M₂₁ ). This is a fundamental property of mutual inductance, often referred to as the reciprocity theorem for mutual inductance. So, Assertion (A) is true. - Reason (R) states that mutual inductance between coils is independent of the current passing through the coil. Mutual inductance (M) is a geometric and physical property of the coil arrangement (number
