Solve the H-J formulation of Maxwell’s equations for the magnetic field h.

We start with Maxwell’s equations in terms of the magnetic field and current density

$$\mathrm{\nabla }\times \rho \mathbf{j}+\mu \frac{\partial h}{\partial t}={\mathbf{s}}_{\mathbf{m}}\mathrm{\nabla }\times \mathbf{h}-\mathbf{j}={\mathbf{s}}_{\mathbf{e}}$$

and eliminate $\mathbf{j}$ using

$$\mathbf{j}=\mathrm{\nabla }\times \mathbf{h}-{\mathbf{s}}_{\mathbf{e}}$$

giving

$$\mathrm{\nabla }\times \rho \mathrm{\nabla }\times \mathbf{h}+\mu \frac{\partial h}{\partial t}=\mathrm{\nabla }\times \rho {\mathbf{s}}_{\mathbf{e}}+{\mathbf{s}}_{\mathbf{m}}$$
