Neodymium Magnets
A neodymium magnet (also knows as NdFeB, NIB or Neo magnet). Its is the most widely used type of rare-earth magnet. This magnet is a permanent magnet made from an alloy of neodymium, iron and boron. They have replace other types of magnet in the many applications in modern products that require strong permanent magnets like DIY, hand craft, free energy magnet motor, science experiment, metal working and home improvement project.

How to separate magnet
1. It is much more easier to slide magnet from ferrous surface than pull it off vertically. Place the two magnets overhanging a single magnet on the edge of a desk or table and slide one vertically downwards. Remember to move the free magnet away until a safe distance to avoid it snapped back together
2. We advise you not to cut or drill the magnets and should buy the special magnets with special cut out like countersunk or hole if need
