magnetic ball, also called Barker ball, is a set of 216pcs n35 grade NdFeB magnet balls in the size of 5mm diameter. And of course other dimensions such as D3mm, D4mm, D4.7mm, D5mm, D7mm and D8mm are also available.
As the NdFeB easily oxidized, all magnetic balls need surface treatment. Compared with the industrial magnets, magnetic balls own rich types of coatings, such as nickel, gold, silver and a variety of colors of paint.
Unlike traditional building blocks, magnetic balls have magnetic forces to attract each other. As long as you imagine the rich enough, you can piece balls together into the ever-changing shape.
If work too long time & tired, under big life pressure, or have too much trouble, you can play about Buckyball. By its deformation, distorted, you can release the pressure.
Buck ball can be used as a teaching tool to improve the imagination of geometric space.
However, do not let the children play Buck ball, because they are easy to swallow the ball into the mouth and cause intestinal perforation. High powered magnets are not children’s toys as well, as they may hurt fingers of children.
