Current flowing in N1 will induce a magnetic flux in the core. Use the right hand rule to determine the direction of the flux.

Now imagine that current is flowing in N2 which itself would induce its magnetic flux. This has to oppose the flux from N1 otherwise you would have perpetually increasing current.
