NdFeB Cube Magnets

When neo (dymium) cube magnets are combined in linear areas, these assemblies produce strongly concentrated magnetic fields. One of the most popular is the Halbach array which can use any size NdFeB cube magnet but the 5 & 10mm are the most popular for this. The 10mm neo cube magnet has a theoretical holding force of nearly 1000 times its own weight!

Each has an axis of magnetization but they are not indicated; a compass or is needed identify the N-S poles.
