Questions
Three identical coils A, B, and C carrying currents are placed coaxially with their planes parallel to one another. A and C carry currents as shown in figure. B is kept fixed,
while A and C both are moved toward B with the same speed. Initially, B is equally separated from A and C. The direction of the induced current in the coil B is
detailed solution
Correct option is C
Because A and C are at equal distance from B, and their flux across B is in opposite direction, so at any time flux in B will be zero. Hence no emf is induced.Similar Questions
