We establish the gravitational detectability of a Dirac monopole using aweak-field limit of general relativity, which can be developed from theNewtonian gravitational potential by including energy as a source. Theresulting potential matches (by construction) the weak-field limit of twodifferent solutions to Einstein's equations of general relativity: oneassociated with the magnetically monopolar spray of field lines emerging fromthe half-infinite solenoid that makes up the Dirac monopole, the otherassociated with the field-energetic source of the solenoid itself (the Diracstring). The string's gravitational effect dominates, and we suggest that theprimary strong-field contribution of the Dirac configuration is that of ahalf-infinite line of energy, whose GR solution is known.
