Maxwell's equations in the covariant form are the most general relations expressing electromagnetic phenomena in the presence of gravity.
Now [tex]\nabla[/tex]B=0
does not follow in a general way as a necessary condition from the covariant form of the Maxwell's equations.
We can always calculate the classical three divergence[does't matter what Maxwell's equations are saying] and if
[tex]\nabla[/tex]B[tex]\neq[/tex]0
B has sources which may be identified with magnetic monopoles, created by the action of gravity!
