Detailed Answer :
As seen from the side of the approaching magnet the current inside the coil should be clockwise so that the induced magnetic pole on the right side of the coil will be ‘south’ which tends to repel the approaching magnet, hence magnet’s field inside the coil points from right to left which induces clockwise current to flow from left to right.
