Stationary, axially symmetric Brans-Dicke-Maxwell solutions are reexamined in
the framework of the Brans-Dicke (BD) theory. We see that, employing a
particular parametrization of the standard axially symmetric metric simplifies
the procedure of obtaining the Ernst equations for axially symmetric
electrovacuum space-times for this theory. This analysis also permits us to
construct a two parameter extension in both Jordan and Einstein frames of an
old solution generating technique frequently used to construct axially
symmetric solutions for BD theory from a seed solution of general relativity.
As applications of this technique, several known and new solutions are
constructed including a general axially symmetric BD-Maxwell solution of
Plebanski-Demianski with vanishing cosmological constant, i.e. the Kinnersley
solution and general magnetized Kerr-Newman--type solutions. Some physical
properties and the circular motion of test particles for a particular subclass
of Kinnersley solution, i.e., a Kerr-Newman-NUT--type solution for BD theory,
are also investigated in some detail.Comment: V2: 18 pages, published version; some references and section VI is
