A)
B)
C)
D)
Correct Answer: D
Solution :
When loop enters in field between the pole pieces, flux linked with the coil first increases (constantly) so a constant emf induces, when coil entered completely within the field, no flux change so \[e=0.\] When coil exit out, flux linked with the coil decreases, hence again emf induces, but in opposite direction.You need to login to perform this action.
