Lenz law :- according to him , if flux associated with a loop change then emf induced in loop having nature to oppose variation of flux .
() ----(N====S)
separation decrease , flux increase . To reduced flux induced field have nature to oppose motion of magnet .
now, in question ================== here magnet goes towards wire distance(↓) so, we have to required flux increases . how flux increases when direction of magnetic field from S to N . hence , here given N to S direction is wrong , put S to N

In the above diagram ,Consider north direction as south and south direction as north (excluding bar magnet)
Current direction remains same

when direction of magnetic field from S to N .
hence , here given N to S direction is wrong , put S to N
