Neodymium block magnets in rectangular, square and cube shapes. 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 shop you can find blocks with heights from 1 zu 150 Millimeter (6 Zoll), which makes them very versatile. The neodymium block magnets contain a protective coating of nickel, some also leaf gilding, which makes them very attractive-looking.
