Blackett effect and Earth's magnetic field

  1. Sep 16, 2006 #1
    I'm looking for information on Blackett's effect in general and the derivation of his fomula in particular.

    Despite what this paper suggests, Blackett's effect does not exist. Electrically neutral rotating masses do not produce magnetic fields. So the only "information" you will find on it will say that it does not exist. You may find misinformation, like this paper, that will suggest otherwise.

    Whether this phenomenon really exist is of little importance to me.
    What I'm interested in is how he got to that formula.
    Btw, neutral rotating masses do produce minute magnetic field due to small effects like thermal current fluctuations, centrifugal forces, gravity etc.
