Why is there a correlation between gravitational and magnetic fields?

  1. Mar 10, 2013 #1
    A gravitational field and a magnetic field both decrease in strength at the distance squared. They are two totally different forces so why the correlation?

    no its not that complex -- Invalid ID ;)

    read all about it here on wiki

    its also the same for an E-M wave ( light, radiowave )

    So is it fair to say that divergence is what they have in common?

    The vanishing divergence without sources in the common reason for both inverse square laws, indeed.
    To have a magnetic field decreasing as inverse square law, you would need (unobserved) magnetic monopoles, however. It is easier with electric fields.
