Some of the more famous examples include Maxwell in 1855 who showed electric and magnetic lines of force could be described by a single set of equations; Einstein died working on a unified field theory to explain the relationship between gravitation and electromagnetism and more recently, the 1999 Nobel Prize was awarded for work toward deriving a unified framework for all the theoretical forces (Gerard 't Hooft).
Giant reservoirs of hot magma?
Yes, there is a possibilty that the two forces are linked at some fundamental level, just as the Strong and Weak forces possibly are. You are confusing unification with application. You cannot possibly duplicate a gravity field from an electro-magnetic source.
As far as magma power, no, it does not quite work that way. You need an electric flow through a coil to induce a magnetic field, and there is no possible way that the heat from magma could do this, without a man-made mechanical component that is.
Ah, and the whole thing is irrelevant anyway because seismic data proves its not hollow.
