With school I don't have much time to experiment with my electronic equipment, but I had a little time a couple weeks ago to see what the effects of pulsed dc electricity had when it was traveling through copper wire wound around a toroidal ferrite core. I found that the properties of the square wave (from the pulse generator) changes at two points - where the pulse starts and ends. It seems as if there is a decreasing resonance being generated from the ferrite core. I'm wondering if this is what is known as hysteresis. I only had time to try out one frequency, so next time I fire up my equipment I'll try different frequencies. I also tried subjecting the ferrite core to a sawtooth wave, but it didn't seem to have any resonating effect. Once I complete my step up transformer I'd like to see what kind of waveform I get on the oscilloscope. The step up transformer will consist of a torodial ferrite core wound with 200 turns of 24 AWG magnet wire as the primary and 600 turns of 36 AWG magnet wire for the secondary.
