I am designing a transformer in FEMM and I was wondering about the polarity of the windings. The following figures illustrate two cases.
When I run the simulation, the magnetic field in the first one is significantly bigger than in the second case so I guess the first one is the right.
Am I wrong? What parameter defines the polarity of the windings.
EDIT: There is a small mistake in the pictures. The 24 AWG / 1000 turns is the primary winding. There is a mistake with the name.
