Homework Statement
Three wire loops and an observer are positioned as shown in the figure below.
From the observer’s point of view, a current I flows anticlockwise in the middle
loop as that loop moves towards the observer with a velocity of v ms^-1
Loops A and B remain stationary.
In what direction are the induced currents in Loops A and B
Homework Equations
None, use Lenz's Law
The Attempt at a Solution
Using the right hand grip rule for solenoids, i got the effective N pole of the middle loop to be directed to the left, i.e directed towards the observer.
So Loop A would want to create a N pole in the direction of the middle loop to oppose the change, which using the right hand grip rule for solenoids again, means the current would be flowing anticlockwise.
Loop B would want to create a S pole to oppose the change made by the effective south pole of the middle magnet moving away from it. So the induced current would also be clockwise.
I really don't have much of a clue whether I am right, i tried to give it to my teacher but he's worse at physics than half of our class so that was a bit pointless. Anyway any help will be appreciated.
