Buying a set of 10-20 magnets!

I am buying a set of magnets to attempt an experiment (I know, quite geek like). I would like 10-20 CIRCULAR DISC magnets. They cannot have adhesive on them, as this will not give the desired effects for my experiment.

If you have these magnets, please add my MSN: [email protected]

Also looking for 10-30 Steel Ball Bearings of just under an inch diameter.

Thanks,

Panda
P.S There is a reward for anyone who can add my MSN and tell me the experiment I am doing if they know it.
