Various techniques are then used to find solutions to the field equations. The fact that the field lines corresponding to these solutions have the common feature of being twisted, and may be knotted, motivates a discussion of field line topology and the concept of helicity. The topics of field topology, helicity, and magnetic energy in multiply connected domains make the book of interest to a rather wide audience. Applications to solar prominence models, type-II superconductors, and force-reduced magnets are also discussed. The book contains many figures and a wealth of material not readily available elsewhere.Contents: IntroductionThe Virial TheoremSolutions to the Force-Free Field EquationsField TopologyMagnetic Energy in Multiply Connected DomainsApplicationsForce-Free Fields and Electromagnetic WavesProof of the Jacobi Polynomial IdentitiesSeparation of the Wave Equation, Cyclides, and Boundary ConditionsReadership: Students and researchers working in physics, astrophysics, hydrodynamics, plasma physics and energy research.
