The magnetic dipole interaction in Einstein-Maxwell theory
W. B. Bonnor
I derive an exact, static, axially symmetric solution of the Einstein-Maxwell equations representing two massless magnetic dipoles, and compare it with the corresponding solution o…
Interaction between a stationary electric charge and a stationary magnetic dipole
W. B. Bonnor
Using Einstein-Maxwell theory I investigate the gravitational field generated by an electric charge and a magnetic dipole, both held in fixed positions, but spinning with prescribe…
Classical gravitational spin-spin interaction
W. B. Bonnor
I obtain an exact, axially symmetric, stationary solution of Einstein's equations for two massless spinning particles. The term representing the spin-spin interaction agrees with r…
An exterior for the Gödel spacetime
W. B. Bonnor, N. O. Santos, M. A. H. MacCallum
We match the vacuum, stationary, cylindrically symmetric solution of Einstein's field equations with , in a form recently given by Santos, as an exterior to an infinite cylinder…
