  We establish the gravitational detectability of a Dirac monopole using a
weak-field limit of general relativity, which can be developed from the
Newtonian gravitational potential by including energy as a source. The
resulting potential matches (by construction) the weak-field limit of two
different solutions to Einstein's equations of general relativity: one
associated with the magnetically monopolar spray of field lines emerging from
the half-infinite solenoid that makes up the Dirac monopole, the other
associated with the field-energetic source of the solenoid itself (the Dirac
string). The string's gravitational effect dominates, and we suggest that the
primary strong-field contribution of the Dirac configuration is that of a
half-infinite line of energy, whose GR solution is known.
