Any charts for ceramic bearings so you don't need to worry about magnetism??

BTW, I did a demo of magnetism with non-magnetic materials.? Dropped a strong magnet through 200cm of 10mm copper tube.? Took a while to fall out the other end, something nobody in the room had seen or expected.

I did include a wave of a Harry Potter magic wand, just for extra effect.
