Question
Loop A of radius (r < < R) moves towards loop B with a constant velocity V in such a way that their planes are always parallel. What is the distance between the two loops (x) when the induced emf in loop A is maximum -


Options
A.R
B.
C.
D.R
Solution
φ = BA = 
e =
For e to be maximum
= 0 ⇒ x = 
e =
For e to be maximum
