But it's not working.
I'm not sure why.
I made some nice coils out of the coil I made before. I unravelled it and thought I should try to explore the relationship between the number of turns on my coil, and what I see on my multimeter.
I started by making a cardboard tube coil winder. I figured it would be best to at least have the size of the coil consistent. I found a few different designs to make a coil winder and all the good ones shared a few points.
This looks pretty dismantleable to me. In fact it's trying to dismantle itself just because I'm looking at it.
The object here is to create a frame to coil the wire in so that it stays nice and neat.
Once it's through, you can hold the tape and the device in your left hand and add coils of wire with your right hand.
When you have added the desired number of coils you can mess about in such a was as to fold the tape over the coil before you dismantle the device.
Its best to work with a real friend, unlike the imaginary one I retain.
Thanks for nothing Ted.
I successfully made three neat and well formed coils.
One each of 25 turns, 50 turns, and 100 turns.
That is, it worked quite well until the making the electricity bit.
That bit didn't go so well.

Here is the magnet rotating device (a stick with a magnet stuck to it attached to a motor) pictured top without the flash, and bottom, with flash to freeze the image so you can tell its there.
The bit of wood sticking out to the left holds the magnet. All the other tackle is as counter-balance to stop all the stuff on my desk from vibrating away. Unbalanced motors vibrate a lot.
The point here is that I had the magnet spinning over the coils very fast and quite close and got as close to zero result as I could, without simply not turning up on the day.
In the first test I did, I spoke of the electrons surging around within the coil. Those were my words, but I'm not sure I understood them. What if it wasn't just the magnet passing first on side of the coil then the other, but the simultaneous passing of the south pole on one side and the north pole on the other. Magnets have poles by the way. Actually I read they don't and magnetic poles are an illusion, but the site I read that on was way out of my league, so for now I'm sticking with "Magnets have poles". Sometimes illusions are handy.
So things that I might have done wrong possibly include, but are not necessary restricted to...
1. I used less magnets than my first attempt. Perhaps this arrangement wasn't powerful enough.
2. I had only one magnet. Perhaps I need a north and a south pole hitting opposite sides of the coil.
3. I had less turns on my coils. Even the biggest one had only 100. My first attempt had 157.
4. Perhaps my magnet was passing the coil slower. Or too fast???
5. Something/everything else
Its possible that there is a certain threshold below which you get nada, then suddenly you make some power. Some things work like that. I can't think of anything that works like that, but there must be some things that do.
Whatever it is, rest assured, I'll get to the bottom of it. I often finish what I start.
