get_magnetic_field#
- emg3d.fields.get_magnetic_field(model, efield)[source]#
Return magnetic field corresponding to provided electric field.
Retrieve the magnetic field \(\mathbf{H}\) from the electric field \(\mathbf{E}\) using Farady’s law, given by
\[\nabla \times \mathbf{E} = \rm{i}\omega\mu\mathbf{H} .\]Note that the magnetic field is defined on the faces of the grid, unlike the electric field which is defined on the edges.
- Parameters:
- modelModel
The model; a
emg3d.models.Model
instance.- efieldField
The electric field; a
emg3d.fields.Field
instance.
- Returns:
- hfieldField
The magnetic field; a
emg3d.fields.Field
instance.
