I posted in November to on problems I was having with coil geometry, Using 1/2"X1/2"X 2" N48'S I was getting very strange readings. Well We had a very busy holiday season and I Finally got back to it. I got it working and discovered my mistakes...at least some of them. I made a 3 x 3 square coil with 150 turns, slipped in an old motor rotor with 2 magnets stuck on it, one north, one south opposite each other. I attached the drill and spun it at 1100 rpms and got about .5 volts. I had a rather large gap between the magnets and coil at about 3/8" each side. I now realize that each side of the coil needs to be exposed to an opposite pole at the same time to get electrons flowing! duh... smaller air gaps give more current... and lastly, I will not get an accurate estimate of it's potential unless I mount up something stationary and quit trying to hold it by hand. Thanks to all who helped me! I've got lots to think about.
