## Magnetic Energy, Multiply-Connected Domains, and Force-Free Fields

Phys. Rev. A Vol. 46, p. 2117 (1992) (PDF)

This paper addresses the question of magnetic energy in multiply connected domains. It is shown that the magnetic energy must in general include a boundary term that is usually assumed to vanish. The physical interpretation of this term is discussed in terms of De Rham’s theorems.
