A possible new galvanogyroscopic effect which is the rotational (gravitomagnetic) analog of Hall effect in electromagnetism has been proposed. As a consequence of a generalized Ohm's law, the effect of the Coriolis force on the conduction current is predicted to give rise to an azimuthal potential difference Vgg in a spinning rotor carrying radial electric current i_r. The potential difference developed by the galvanogyroscopic effect is proportional to angular velocity Omega and to the electric current both. An experiment is proposed for measuring the earth's gravitomagnetic field by using galvanogyroscopic effect. Due to the Lense-Thirring effect potential difference about 10^{-19}V will be developed in a current carrying conductor on a platform which is nonrotating relative to the distant stars.
