You can used this strong neodymium 25x10x5mm block magnet in a Halbach Generator. See below for more information. If you are prototyping a similar device, you can view all our 5mm thick blocks

A Halbach array uses the placement of permanent (usually neodymium) magnets to customize the shape of a magnetic field. It does so by strengthening it on one side while weakening it on the other. The simplest analogy would be to alternate the position of horseshoe magnets so that similar poles touch.

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

Go to Thingaverse for more information on how to 3D print this generator. The page indicates it was made with a 15x5x5mm magnet which we don't have as well as this the 25x10.2.5. However, the designers at Akinora smaller ones such as the 12.5x5x5mm will also work but are out of stock.
