Introduction to the Magnetic Treatment of Fuel By R.J. Kita Hydrogen is the lightest and most basic element known to man. With its simple structure comprised of only one proton and one electron‚ it is one of the major constituents of all hydrocarbon based fuels. By studying the response of hydrogen with respect to magnetic fields and the accompanying increased energy output‚ much can be learned and applied to other related fuels. In the oxidation/combustion of hydrocarbon fuels‚ it is the outer shell of the
