Magnetogram-matching Biot–Savart Law and Decomposition of Vector Magnetograms

We generalize a magnetogram-matching Biot–Savart law (BS l ) from planar to spherical geometry. For a given coronal current density J , this law determines the magnetic field $\widetilde{{\boldsymbol{B}}}$ whose radial component vanishes at the surface. The superposition of $\widetilde{{\boldsymbol{...
