How to plot primary magnetic field B?

[MiroPol21]

Dear all,
I would like to plot the primary magnetic field B = $\mu_0$(M + H). Is there a better way than this?

H = StrayField(magnet, Grid((nx, ny, nz)))
M = MU0 * magnet.full_magnetization()
world_help = World(cellsize=(length, width, thickness))
magnet_help = Ferromagnet(world_help, grid, name="helper magnet")
magnet_help.magnetization = M + H()
plot_field(magnet_help.magnetization)

Perhaps a way to keep the vector size, since assigning the values to magnet.magnetization normalizes the field.
Thank you all for your help.

Sincerely,
Miroslav Polach

Hi

The plot_field function is able to visualize raw numpy arrays as well. This omits the need to assign any custom combination of mumax+ FieldQuantities to new helper magnets. More details about this can be found in this notebook. In your case, this would become something like plot_field( H() + M ).

The plot_field function is very rich. A detailed description about all arguments and parameters can be found here.

Hope this helps!
