Electromagnetic induction problem ..
1. The problem statement, all variables and given/known data
What is the direction of current in ring 2 if :
a) ring 2 moves towards ring 1
b) ring 2 moves away ring 1
3. The attempt at a solution
I used Fleming right hand rule but i'm not sure if it is true,
a) the direction same as ring 1
b) the opposite of ring 1

So the by faradays law the change in the system will induce a current which opposes the change, so when you move the first ring closer, it will produce a current in the opposite direction to loop so that loop 2 is pushed back to its initial position.
And if loop 2 is moved away from loop 1 a current will be produced in the same direction as loop 1 so loop 2 is pull back towards loop 1.
I'm pretty sure thats right
have a look at the first and lasts posts
