  The Gross-Perry-Sorkin spacetime, formed by the Euclidean Taub-NUT space with
the time trivially added, is the appropriate background of the Dirac magnetic
monopole without an explicit mass term. One remarks that there exists a very
simple five-dimensional metric of spacetimes carrying massive magnetic
monopoles that is an exact solution of the vacuum Einstein equations. Moreover,
the same isometry properties as the original Euclidean Taub-NUT space are
preserved. This leads to an Abelian Kaluza-Klein theory whose metric appears as
a combinations between the Gross-Perry-Sorkin and Schwarzschild ones. The
asymptotic motion of the scalar charged test particles is discussed, now by
accounting for the mixing between the gravitational and magnetic effects.
