Description of the circuit to create the results I have posted. If you are wanting to build an alternator I used 24gauge wire wrapped 70times and made the core 1/8 of an inch wider than the magnet and stretched it to the length of the magnet. The smaller the wire the more turns you need and visa versa. 20 gauge you may only need 40turns and 26gauge you will do 100-200 turns. There is a "sweet" spot you have to experiment with to get the most gain out of the RPM's your motor turns. I used a "star" 3phase wiring with thinner wire to gain more volts and less amps. It bogged a LOT less with this setup than with the single phase 22gauge wire 100turns. Your choice. Just know that you need 3 coils for every "N S" magnet. The coils can be stacked slightly out of phase if you have many magnets or did what I did which is to have wide magnet space so I didn't have to stack my coils.
