Amperage for Gauss
My calculations place the 3" diameter Neo ring magnet at around 2000 Gauss. That would require around 20 Amps of input my into ferrite core bifilar of 121mH to neutralize the strength.
The sturdy latching Reed switch commutator contacts I designed should be able to handle this high a current. The output may be over 3 times the input. I measured the Ohmic resistance of the small Electro-magnet coil and it was nearly identical to the bifilar resistance, both reading nearly the same inductance with the bifilar as air core. Both the Electro-magnet and the bifilar coil have stranded wire. The only explanation for this would be the tightness of the factory wound Electro-magnet.
Lower voltage avoids sparking and power loss through induction seepage. I need to shop for an amperage regulated power supply. The output would be enough to run a household electric furnace!
Naturally the addition of magnet spacers would lower the I/O.
