These are the coils, plus the drill, that I have been experimenting with by spinning them, with the drill, between the magnets in the vise. The small one did not light the Christmas bulb at all, even on full speed, but the large one did, and it is the one that produced that faint glow in the bulb filament.

Hi,

Sorry it took me a while to get back to you. I was swamped with spam posts, literally thousands of them.

Your coils need to be wound on a spool with metal in the middle Soft iron is best. Make the coils stationary and spin the magnets past the coils. Get the magnets as close as you can to the coils without hitting them.

Hope this helps some.

Hey in addition to techman2015's advice I mix brake rotor shavings with an epoxy and placed coils around those cores. It reduces the hysterisis loop with iron saturation.

Check mechanic's shops thats were I get them. They will usually have 5 gallon bucket worth.

just my thoughts thought

best of luck to you.
