ALNICO MAGNET TYPES
Magnetic flux is measured in Gauss - this is an indication of how strong a magnet is capable of being. Magnetic field intensity is measured in Oersteds. Technically speaking, the strength of a magnet is best measured as an approximate combined product of the Gauss and Oersteds. This is somewhat analogous to how electrical power in Watts is the product of Volts and Amps (Volts x mA = Watts). For example, 40 mA at 250 volts (40 x .250) produces 10 watts per tube, and the same 40 mA at 500 volts (40 x .500) produces 20 watts. So, when considering magnetic strength, ultimately, both Gauss and Oersteds are factors. That said, I'll keep the scope of this article to the commonly used measurement of Gauss, as such understanding provides sufficient insight into magnetic properties relating to guitar...
