Teddy, Lesson on E and M, Electricity and Magnetism. You can't have one without having the other. Magnetic fields are a right angle to the direction the electrons are traveling.
One way to measure magnetic strength is with amp-turns. Double the turns of wire, and you double the magnetic strength. Same with doubling the amps, you double the magnetic strength.
According to Ohm's law, doubling the voltage in a DC circuit, you will also double the amps.
In theory, if you were to use a 6v starter on a 12v battery you will double the amps. According to the laws of physics, power is equal to volts times amps. Twice the voltage and twice the amps, you have 4 times the power.
My dad converted an old case tractor over to 12v and he used the old 6 v starter. We just had to bump the starter and the tractor was running.
When tractors are converted over to 12v, are the starters replaced with 12 v starters, or do some of you do like my dad? I don't ever recall replacing the 6v starter on the case.
Where did you come up with E=MC squared? E stands for energy, M is mass and C is the speed of light. This is high energy physics where you have fission or fusion and a loss of mass, not to make things more confusing :)

Today's Featured Article - George's Fordson Major - by Anthony West (UK). This is a bit of a technical info to add on to the article about George's Major in the "A Towny Goes Plowing" article. George bought his Major from a an implement sale about 18 years ago for £200.00. There is no known history regarding its origins or what service it had done, but the following work was undertaken by Harold alone to bring it up to show standard. From the engine number, it was found that the major was produced late 19
