A neocube is made of tiny balls made from the best magnetic (non electric) material called
neodium.
There are all kind of sizes (and strength) for them, but the most common is 5mm.
What the difference between buckyball and
neocube?
Answer:
A buckyball is made of C60 (carbon). Where a neocube is made up of an
alloy of Nd2Fe14B (Neodymium, iron and boron). Which is the
same alloy as a standard hard drive magnet.
