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 left side of the coil is 'south' and it tends to repel the approaching magnet(Lenze's Law), hence the magnet's field inside the coil points from right to left(opposite to the ...
