Block Magnet  
Neodymium Bar, block & cube magnets strong neodymium rare earth block/bar magnets are incredibly powerful for their size and ideal for use in manufacturing, science experiments, woodworking, crafts, DIY and hobby projects


Arc Magnet
Strong Neodymium Arc magnets are used in building motors, generators or magnetic bearing. Since neodymium magnets N35,N36,N42,N45, 50 & N52 are much stronger than other magnets, using strong neodymium magnets can build much more powerful motors, generators ever
