I'm not quite sure what you're on about here.
I've tried it both ways. Magnets NSNS and magnets NNNN. I get a nice sine wave either way, but the NSNS changes the polarity of the wave, each cycle. I think it moves the field back and forth and the speed of the move makes for more voltage, but that is just my guess.
Also, I have observed that the wave peaks and so does the voltage, when the center of the magnet is over the center of the coil. I have read contrary opinions in this forum, like leg excitment. What's right?
I'd be interested in how to get DC current from spinning a magnet over a coil, without rectifying the voltage, if it can be done. I don't have the book, so a simple explanation would be appreciated.
On the subject of the Bedini motor, I have tried a new transistor, a 2N3055HV and observe a somewhat different trace than from the 2N3055 I bought at Radio Shack. Just prior to the closing the circuit and initiating the pulse there is a brief voltage spike that exceeds 20 volts. I think this is what Bedini calls radiant energy. There is no explanation for it I can see, and I don't know; where does it come from? The battery voltage doesn't ever exceed 5 volts. With this chip, it seems to stay on between pulses, being modulated to about 8 volts by the positive coil wave. Also, at the end of the pulse there is another 20+ volt spike of cemf; this is the current stored in the inductor that is released when the circuit is opened I think, which is well documented in literature. Since all this voltage is changing value, all the time in this chip, it all should be able to be captured by a secondary winding.
If the secondary winding is of heavier gauge wire, than the primary, will the current out be greater? Don't know. Just asking. Not trying to create controversy.
