Electromagnetic induction problem

Homework Statement

What is the direction of current in ring 2 if :

a) ring 2 moves towards ring 1
b) ring 2 moves away ring 1

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
