SUMMARY
The discussion clarifies that the electromotive force (emf) in a solenoid is expressed as E = N * d(phi)/dt, where N represents the number of turns. This formulation indicates that inductance is indeed proportional to the square of the number of turns, as both the magnetic flux and the emf depend on N. The confusion arises from the dual consideration of N in the equations, which leads to the conclusion that increasing the number of turns enhances the inductance due to the relationship between flux and emf.
