KVPY2011PhysicsMagnetic Effects of Current
A rectangular loop of wire shown below is coplanar with a long wire carrying current I . The loop is pulled to the right as indicated. What are the directions of the induced current in the loop and the magnetic forces on the left and the right sides of the loop?
Options
- AInduced current - Counterclockwise, Force on left side - To the left, Force on right side - To the right
- BInduced current - Clockwise, Force on left side - To the left, Force on right side - To the right
- CInduced current - Counterclockwise, Force on left side - To the right, Force on right side - To the left
- DInduced current - Clockwise, Force on left side - To the right, Force on right side - To the left
Correct answer
B. Induced current - Clockwise, Force on left side - To the left, Force on right side - To the right
Step-by-step solution
Flux is inward and it is decreasing as loop is going away from wire direction of induced current is clockwise Force on left side is in left and force on right side is in right.
