The discontinuities of electromagnetic test fields generated by general layers of electric and magnetic
monopoles and dipoles are investigated in general curved spacetimes. The equivalence of electric currents
and magnetic dipoles is discussed. The results are used to describe exact ‘‘Schwarzschild disk’’ solutions
endowed with such sources. The resulting distributions of charge and dipole densities on the disks are
corroborated using the membrane paradigm.
