One magnet no bearing Bedini motor

Wilby:

Glad to see you are replicating this.  This is one of the coolest things to have running right in front of you.  As I found out, the magnets make a huge difference in running attitude...lucky for you have have one that goes vertical in a steady way.  If not for Jonny, I would be stuck with my X wobble.  I did a pretty nice job tonight on mounting a computer fan (turbine) onto one of the eggs.  It was well centered and well balanced but....there is a metal ring on the ID of those fans, (after you remove the magnet) and I decided to leave it as I might have damaged the fan by removing it.  Well, big mistake.  I got everything else ok but the metal messes with the field and it spins, but does not even go near the center and when it does....it flops over.  I tried every setting I have but it has to be that metal in the core.  I will try removing it for next time.

There are so many things we can do with these.  I am taking Jonny's suggestion and after modding my circuit like his, I will try to run it on the earth battery....which is now up to 12 mA's as of just a little while ago. (@1.96 volts)

I hate it when an experiment does not work as planned but, that's the way it goes.

thanks pirate. yeah it was pretty sweet to see it spin right away. i used one of those 'perpetual motion' toys. has a little kicker coil in the base, no adjustments. now i need to do a proper build. your fan sounds interesting. you might discover a 'new' kind of magnet 'lift' with that 

@ all
do you guys think a u shaped core, with enough separation between the two poles, would spin two magnets?

@WilbyInebriated:

The 2nd magnet would have to be brought in at the exact speed and phase of the first magnet onto the 2nd core-end
or it would interfere the first magnet's push from the transistor.
I guess that is close to impossible.
Even if you would manage somehow to do that, the amp-draw would simply double, no real benefit in using two magnets hypothetically.
To understand that, i recommend watching this MIT professor explain how this magnet motor works:

The magnet and the transistor work together in sync.

I had to play a little last Sunday. I wound a 26 guage coil around the plastic jar to check on electric generation. The coil was only about 60 feet of wire - did not count the winds. The coil produced a small voltage when surrounding the magnet and also when held outside of the magnet at a 90 degree position. The interesting part was the jump it took when held at about a 15 degree angle as you can see in the video.

Perhaps Xenomorph or someone else could see if holding the coils similarly to the vid increases the volts. Mine went from .2 to almost 4 volts AC.

@ brownsville:

Great vid man.  I don't know why this could be.  I too will try this.  I have tried a roll of 30 ga. mag wire and could not get much at all out of it.  I will post my results.  Great job.
