It was originally thought that Bonnor's solution in Einstein-Maxwell theorydescribes a singular point-like magnetic dipole. Lately, however, it has beendemonstrated that indeed it may describe a black {\it dihole}, i.e., a pair ofstatic, oppositely-charged extremal black holes with regular horizons.Motivated particularly by this new interpretation, in the present work, theconstruction and extensive analysis of a solution in the context of theBrans-Dicke-Maxwell theory representing a black dihole are attempted. It hasbeen known for some time that the solution-generating algorithm of Singh andRai produces stationary, axisymmetric, charged solutions in Brans-Dicke-Maxwelltheory from the known such solutions in Einstein-Maxwell theory. Thus thisalgorithm of Singh and Rai's is employed in order to construct a Bonnor-typemagnetic black dihole solution in Brans-Dicke-Maxwell theory from the knownBonnor solution in Einstein-Maxwell theory. The peculiar feature of the newsolution including internal infinity nature of the symmetry axis and itsstability issue have been discussed in full detail.Comment: 29 pages, Revtex4, Int. J. Mod.
