This presentation details the design considerations and the influence of magnetic material choice on the ability to magnetise a permanent magnet assembly. Initially the presentation focuses on the magnetisation characteristics of NdFeB and SmCo. This is followed by the impact of the way that the permanent magnets are arrayed and the influence that this has on the required electromagnetic field. Finally a series of examples derives a general rule for the magnetising of rotating magnetic assemblies in either NdFeB or SmCo.
