An important point about an ideal transformer is that the reluctance of the core is zero, this means in the magnetic circutit the sum of the magnetomotive force ( ƩN*I) must be zero otherwise the flux would be infinite. This results in the relation

I2/I1=N1/N2

And the ration happens to be the inverse of the voltage ratio.
