I just took physics 2, electromagnetism, and I'm pretty sure you can't. I know magnetic flux is involved, but I don't think the equations interact that way. Anyways, I was more talking at the basic idea of what Gauss's law is - that is the electric field times the area it goes through equals the electric flux.
i think you've learned just enough to be dangerous. 
Gauss' law does apply to magnetic flux, but the net is always zero, meaning magnetic monopoles don't exist. Whereas the net electric charge on a surface caused by electric monopoles (electrons) leads to an net electric flux, the absence of magnetic monopoles leads to a net magnetic flux of zero.
Indeed. Gauss' Law is a mathematical statement that applies to any field: electrical, magnetic, graviational, even the field of a moving fluid like water in a stream. It describes the relationship between any sources or sinks of the medium and the field at a surrounding surface. It's most important in elctrostatics since point sources exist. In Maxwell's equations the magnetic statement of Gauss' Law is equally important, divB = 0, so no magnetic point charges exist.
