Question
Two identical circular coils A and B are placed parallel to each other with their centers on the same axis. The coil B carries a current I in the clock wise direction as seen from A. What would be the direction of the induced current in A seen from B when (i) The current in B is increased (ii) The coil B is moved towards A keeping the current in B constant
Options
A.clockwise, clockwise
B.clockwise, anti clockwise
C.anti clockwise, clockwise
D.anti clockwise, anti clockwise
Solution
I increases B1 increases
So from Lenz′s law
Current in A is clockwise
I same and flux linked with A increases
So from Lenz′s law current in A clockwise
