The NdFeB (NIB) magnets, in disc, ring and rod forms, are usually axially magnetised (the round ends are the magnet poles). Diametrically magnetised discs and rings can be produced upon request (looking at the circular end face, the magnetism runs from the 12 o'clock position to the 6 o'clock position in diametrically magnetised magnets). Likewise, the rectangular blocks can be specially produced to be magnetised in any of the three axes (the magnets cannot be re-magnetised in another axis due to the method of production – the sintered NdFeB is anisotropic). Arcs, trapezoids and other shapes and assemblies (e.g. Pot Magnets, Separator Grids, etc) can generally also be produced. Bespoke Directions of Magnetisation within the magnet shape may also be possible (subject to confirmation) e.g. for Halbach Array assemblies.
