Abstract :
We present a mixed formulation for magnetostatics in unbounded domains. The magnetic flux density B is the principal unknown and it is interpolated with facet finite elements. The reduced scalar potential φ, which is considered as a Lagrange multiplier, is an auxiliary unknown; it is taken as constant over each tetrahedron. We compare it with a previously presented H-oriented mixed formulation
