... Lenz's law is illustrated in the diagrams: As you move the N-pole into the coil, an e.m.f. is induced which drives a current round the circuit as shown. Now use the right-hand grip rule Can you see that the current produces a magnetic field with a N-pole at the end of the coil nearest to the magnet? ...
