I understand what Ohm's law says, but what I don't understand is where all those extra amps are coming from. Lets take 4 6 volt batteries with 500 CCA each. If we hook them up in series we get 24 volts but the amps stay the same. If we hook them up parallel they stay at 6 volts but the amps go to 2000. Then put them in a JD diesel hooked in series it turns over and starts normally. But if we hook them in parallel it won't turn over & start. Hold it long & it will burn off the brush leads. So this tells me that the magnetic field comes from the VOLTAGE not the amps. A permanent magnet has no current, so the field has to be coming from the atoms of the material. So with an electromagnet the field comes from the atoms of the windings excited by the VOLTAGE. Geo put a small lawn mower battery in his C & was satisfied that his starter turned & started it without the slam-bang he had earlier. But lets take a battery of the same size (if you could find one) in 6 volts. The amps would be higher because the cells are twice as big. But I am willing to bet, it won't turn over & start the engine. Once again proving it is the Voltage not the current making the stronger field. If you are doubling the amps by going from a 6 to 12 volt battery, the size of the battery would have to double too. Unless you are getting something from nothing! Also how do all those extra amp's get through the 12 volt cables that are only half as big as those used with a 6????????

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK). There is no known history regarding its origins or what service it had done, but the following work was undertaken alone to bring it up to show standard. From the engine number, it was found that this Major was produced late 1946. It was almost complete but had various parts that would definitely need replacing.
