Al:

Here is where I got mine:

http://www.magnet4less.com/index.php?cPath=13&osCsid=a868f027ba7724ab79125c2c77ca7a49

$4.40 ea.  Watch the minimum order as I was going to get 3 but was able to get 5 for just a dollar or two more.  These, as all of them probably are, are so strong, if 2 get stuck together, it is very hard to get them apart.  I am still pretty strong and I am telling you it took me 5 minutes last night to get 2 of them apart.

@Xenomorph.Nice work with the levitating satelite.I wonder if you could introduce rotation by bringing in a slave coil?
Regarding your feedback to source circuit.You may be able to use optocouplers as these will isolate the coils.
Have you seen comwarriors vids on feed back to source?
He is using optocouplers and this may give you some more options and idea's.
@Pirate.Hi Bill.Your setup should be great for spinning the cylinder and satellites now you have removed the core.Is what you need to do to get the satellites going is first drop your voltage right down.I would try two AA batteries first and you can always add more later.The satellites are spinning in the rotating magnetic field and if it is rotating to fast the satellites can't react to it.
What kind of containers are you using for the satellites?I use small plastic containers with a slight taper for the orbiting satellites.If these are paced upside down with the taper facing down,the 6mm sphere rotates in a nice flat orbit.You just give these a quick flick with your wrist and these start.This type of satellite is not as good for induction as the stable satellite.
The stable satellite is easy to do.You just need to contain the sphere in a very small container.I have been using tops of washing up liquid bottles,the type which has a push pull plunger.I posted a pic earlier of this type.I have used ice cube trays but you need to tilt the tray so the spheres are resting against the front wall.
Now the trick to starting the stable one's is this.Place your satellites about 6"  away from your rotor and then give your cylinder rotor a slow WOBBLY spin.It's the intial wobblyness of the rotor which starts them up.You should here a crackling noise like rain on a tin roof.You can start more by holding them close to the rotor until you here them crackling and then move them away and they will keep going.
You can use a pick up coil to light a led to show you they are generating.I would makeone using 40 swg mag wire as i seem to be able to recover quite high voltages with mine.A coil from a relay is even better if you can find one where you can fit the sphere inside the hole where the core used to be.
So to sum up Bill.Drop your voltage and a nice wobbly initial spin should get you going.
@Gadget.Hi Al.Sounds like you are having some fun now ay.I think the cyinders are more economical than the snake eggs so you may see a further reduction on your already miniscule current draw.Happy experimenting.
@Brownsville.Hi and thanks.I am glad you are still with us and quietly working away.Nice job with the six satellites of a snake egg.Try and get a cylinder if you can and thanks for the info

Thanks Jonny . your on to something here . I am Now an Affiliate for the BIG FAT TUBE Diametrical Magnetized MAGNETS . they are in two sizes  the largest is 1 inch X 1 inch and very Strong and Cheap . If interested Click on the picture of them on My Site and you will be redirected to the Applied Magnetic s  . Many Thanks if you do get them from that link www.sunpowerwindpower.com . Thanks and Happy Experimenting !!I'm having fun !

A made a test with a reed switch to isolate the circuit while discharging a tertiary winding into the source but it does not work as expected.
Since the school boy motor runs at very low RPM too, i even tried it with zero base resistance and low voltage because i also found out that the reed switch would not let enough radiant energy pass through it at high RPMs even though there is sparks in the reed tube.
I verified this using a 3rd battery and it charged at low RPM but not at high RPM.

Next i will try hall transducers with MOSFETs, which switch faster than reeds but dont isolate completely.

@Jonnydavro: I will look into the opto-coupler variant of the guy, i used a photovoltaic MOSFET driver that also isolates the gate.

@Gadgetmall:

Are you actually using different components than those in Jonnydavros circuit?
I just had the idea you might be using a germanium transistor or something like that to have the magnet spinning at 1mA. Or some kind of tank circuit.
You see my lowest amperage under which the magnet stops rotating is like 3 mA and that is with all resistances set to zero, or maybe your coil is indeed somehow different.
I d like to find a way to speed the magnet up and still run at low amperage and you said you even consider the rotation to be extremely fast.
