Introduce new test cases to validate the forthcoming magnetics implementation: - Add analytical benchmark test comparing induced-only TMI against analytical solutions for a spherical anomaly. - Add symmetry benchmark test to verify induced-only TMI spatial accuracy along a line profile. Also include a placeholder magnetics gradient computation module (`magnetic_gradient.py`) with core physics for initial testing.
Introduce functionality for induced-only TMI anomaly computation using precomputed voxel-based TMI kernels and geologic unit susceptibilities. Updates include: - `compute_tmi`: Core TMI calculation logic based on magnetics kernel and voxel susceptibilities in `fw_magnetic.py`. - Extended `GeophysicsInput` to include magnetics-specific fields such as `mag_kernel`, `susceptibilities`, and `igrf_params`. - Modified `model_api.py` to integrate magnetics into geophysics workflows alongside gravity computations. - Updated `solutions.py` to include magnetics in forward modeling outputs. Ensures magnetics functionality remains optional without impacting gravity workflows.
- Updated `model_api.py` to make gravity computations conditional, enabling workflows without gravity inputs. - Modified `GeophysicsInput` to allow `tz` and `densities` as optional fields for magnetics-only workflows. - Added `tmi` alias property in `solutions.py` for Total Magnetic Intensity outputs. - Improved formatting in geophysics README for better readability.
