Tangential Magnetic Field Condition¶
The tangential magnetic field condition is a boundary condition given by
\[
\left. \mathbf{H} \times \mathbf{n} \right|_{\Gamma} = \mathbf{H}_\text{ext},
\]
where \(\mathbf{H}_\text{ext}\) is the user-defined external magnetic field imposed on the boundary \(\Gamma\).
