Great for Lenz's law demonstration (drop into copper pipe)
Comments about Arbor Scientific Neodymium Magnet Sphere, 0.75", Chrome Plated:
I don't recommend letting children handle these magnets without very close adult supervision. It is very easy to get a pinch... and it can make you bleed.
I bought this ball when I got the magnetic accelerator (in case I lose or break the original magnetic ball). If you have 2 neodymium magnets, it is a lot of fun to experiment with them. Just remember, if you're not careful, there will be blood.

Great match to compare to 3/4" ball bearing
