A small square loop of wire of side \(l\) is placed inside a large square loop of side \(L(L>I)\). If the loops are coplanar and their centres coincide, the mutual induction of the system is directly proportional to
- A \(I / L\)
- B \(I^2 / L\)
- C \(1 / L^2\)
- D \(I^2 / L^2\)
Answer & Solution
Correct Answer
(B) \(I^2 / L\)
Step-by-step Solution
Detailed explanation
A small square loop of wire of side \(l\) is placed inside a large square loop, then mutual induction of the system depends upon. \[ M \propto \frac{1^2}{L} \]
