Seb,
Is there a way to simulate ferrite rods wound with single layer iron wire? Resistance, wire size, turn number, core diameter and permiability can be inputed but I'm not sure if it does that sort of a thing. I don't know much about the simulator but am learning.
The iron wire really works to minimize amps and increases voltages ptp incredibly well. Spintronics is on to something here.
