Rotational Analog of the Hall Effect: Coriolis Contribution to Electric Current

A galvanogyroscopic effect which is the rotational analog of the gravitomagnetic Hall effect has been proposed. As a consequence of Ohm’s law in the rotating frame, the effect of the Coriolis force on the conduction current is predicted to give rise to an azimuthal potential difference $V_{gg}$ about ${10}^{-3}V$ in a spinning rotor carrying radial electric current $i_r$. The potential difference developed by the galvanogyroscopic effect is proportional both to angular velocity $\mathbf{\Omega }$ and to the electric current.
