Magnetostatic field generated by a permanent magnet

Hello everyone,

I have a question regarding the ‘Magnetostatic field generated by a permanent magnet’ example (2.4 Maxwell’s Equations — NGS-Py 6.2.2302 documentation)
[]Most important: Which units do these maxwell tutorials use? E.g. unit each for relative permeability, magnetization and B field?
]If we use a N50 neodymium magnet, what values should we use for mur and mag in the code from the example below?

Kind regards,
