Neodymium Block Magnets
Most block magnets have their north and south pole on the two largest areas. The few exceptions, which are magnetized in longitudinal direction, are specifically marked.These block magnets, like our other super magnets, are made of a special NdFeB alloy, which allows neodymium block magnets to achieve extreme adhesive force of up to 200 kg. In our website you can find blocks with heights from 1 to 25 mm, which makes them very versatile. The blocks contain a protective coating of nickel, some also leaf gilding, which makes them very attractive-looking.
