You can used this strong neodymium 25x10x5mm block magnet in a Halbach Generator. See below for more information.

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.

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. However, the designers at Akinora told us this larger block magnet will work very well. Smaller ones such as the 10x5x5mm & 12.5x5x5mm will also work.
