Question

Statement I: Two coaxial conducting rings of different radii are placed in space. The mutual inductance of both the rings is maximum if the rings are also copanar.
Statement II: For two coaxical conducting rings of different radii, the magitude of magnetic flux in one ring due to current in the other ring is maximum when both the rings are copanar.
A. Statement I is True, Statement II is True, Statement II is the correct explanation for Statement I.
B. Statement I is True, Statement II is True, Statement II is NOT the correct explanation for Statement I.
C. Statement I is True, Statement II is False.
D. Statement I is False, Statement II is True.

Answer 1

Correct Answer - A
It is obvious that flux linkage in one ring due to current in other coaxical ring is maximum when `x = 0`(as shows) or the rings are also copanar. Hence under this condition their mutual induction is maximum.
