Problem
A bar magnet with its north (N) and south (S) poles as shown below is initially moving to the left, along the axis of, and away from a circular conducting loop. A current I is induced in the loop, with a the acceleration of the magnet due to this current. As seen from the magnet looking in the direction of the loop,
[Figure: Shows bar magnet with S and N poles moving left away from circular loop]
(a) I runs clockwise and a points to the left;
(b) I runs counterclockwise and a points to the right;
(c) I runs clockwise and a points to the right;
(d) I runs counterclockwise and a points to the left.
