NdFeB N45 HALBACH ARRAY

The Halbach Array is a specialised magnetic assembly consisting of Rare Earth permanent magnets assembled in such a way as to provide a controlled (uniform and homogenous) and high magnetic field strength without the use of ferromagnetic materials. The NdFeB Halbach Array we offer is a two pole version that is 110mm in diameter with a 30mm diameter central hole. It is 40mm in axial length. It uses standard +80 deg C maximum recommended operating temperature NdFeB (Neodymium Iron Boron). The field in the centre of the air gap is at least 10000Gauss / 1Tesla at ambient temperature. The outer protective sleeve is of brass construction. We can manufacture other Halbach Arrays upon request. Please be aware that the lead time for making the Halbach Array is typically 11-12 weeks.
