Electromagnetic induction problem

  1. 1. The problem statement, all variables and given/known data

    [​IMG]

    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

  3. 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
