We've all gotten used to the idea that Electric and Magnetic fields are real but then we learn about the Aharonov-Bohm effect and suddenly, maybe it's the electric potential and magnetic vector potential are what is 'real'. But then, there's all the issue with gauges. I think that the best way of teaching electromagnetism might still be in the future.
