QUESTION 12 exam 2 aos 1 can someone tell me if this is correct. 
 
- As the magnet moves away from the loop a change in flux occurs.
-This change in flux is opposed by a magnetic field generated to the left.
- This change causes an induced current to flow anticlockwise in the loop.

You missed a few key points. You didn't mention Lenz's law there at all, you need to state the law (Lenz's law states that a change in flux will induce a current with a magnetic field that opposes this change in flux). You should also then state what the change in flux is, in this case it is a decrease to the left.
