Tube magnets are permanent magnets in a tube shape. The tubes made of magnetic material are called magnet tubes or magnetic tubes. It becomes to be a tube magnet when making a hole through the axial of a cylinder magnet. The neodymium tube magnets(also known as tube neodymium magnets) are tube magnets that made from rare-earth neodymium magnetic material. Neodymium tube magnets or NdFeB tube magnets are special neodymium ring magnets, as the height of a neodymium tube magnets is usually longer than the out diameter.
