A rectangular loop is drawn from left to right across a uniform magnetic field perpendicular into the plane of the loop
A
The direction of current in position 1 is clockwis
B
The direction of current in position 2 is clockwise
C
The direction of current in position 3 is anticlockwise
D
The direction of current in position 4 is clockwise
Answer
The direction of current in position 4 is clockwise
Explanation
Solution
No current is induced in position 1, anticlockwise current is induced in position 2 because it is a case of increase of flux, no current in position 3 as there is no change of flux, clockwise current is produced in position 4 because it is a case of decrease of flux.
