There seems to be a misunderstanding on this site as to where the magnetic field comes from. We all have been falsely tought that the field comes from the current. Take a simple 6 volt starter system that turns over but slow. Take out the 6v battery & replace it with a 12 volt that fits in the same box. The starter spins it over much faster, but the amps are less. The cells in the 12 v are only half as big as the 6 volt battery, thus less amps. Another example, Take a 12 volt system using 2 6 v in series. Engine turns over just fine. Then take the 2 6 v & hook them up in paralell to double the amps & it will be a struggle to turn over. Hook another 6v boost to add more amps & it still wont turn very good.Don"t hold it long or it will burn off the brush wires. Amps produce heat. Heat is a waste, it doesn"t make a magnetic field. Then hook the same 3 batteries together in series & it will spin over like crazy. If you check the wattage (volts x amps) in paralell it will be high but not much happening. In series, the faster spinning armature produces a greater back EMF that further reduces the amps. So the wattage is less but it is getting more done. How can that be? You don"t get something from nothing. The magnetic field doesn"t come from the current but from the atoms of the wires excited by the voltage. E=MC squared.
