Although technically you are correct you still fail, when you cross a piece of wire through a magnetic field you induce a voltage. one side will have a positive and one will have a negative. When you only utulize one pole of the field you only get one potential out of it. You must use the north and south pole to get both potentials. So if you use a generator and get half a sine wave out of it that isnt alternating, it has to cross that plane into the other side. Whether or not you smooth out that potential voltage into a steady voltage or not is irrelevant.
Also you use capacitors to smooth out voltage, diodes to change AC to DC, and commuters are people who travel from place of residence to work or full time study
