Question

What is the direction of induced current in the loop when the current in the straight wire is
a) increasing
b) decreasing
1) (a) clockwise (b) zero
2)(a) anticlockwise (b)clockwise
3)(a) clockwise (b)anticlockwise
4) (a) anticlockwise (b) zero​

Answer 1

Answer:

When the current in the wire AB decreases, the magnetic flux linked with the loop will decrease. Hence, the current induced in the loop must be anticlockwise to oppose the decrease in magnetic flux.
