This 1.5" sphere is made of strong neodymium magnet and coated with Ni+Cu+Ni triple layers. There are one north pole and one south pole on the opposite side of the sphere. It is a nice party item.

This magnetic sphere was exactly what we were looking for. It arrived very well packed to avoid any shipping problems and was exactly as described on the website. the sphere is certainly not a toy but is useful for many different demonstrations.
