On the possibility of measuring the Earths gravitomagnetic force in a new laboratory experiment

In this letter we propose, in a preliminary way, a new Earth-based laboratory experiment aimed at the detection of the gravitomagnetic field of the Earth. It consists of the measurement of the difference between the circular frequencies of two rotators moving along identical circular paths, but in opposite directions, on a horizontal friction-free plane in a vacuum chamber placed at the South Pole. The accuracy to our knowledge of the Earthʹs rotation from VLBI and the possibility of measuring the rotatorsʹ periods over many revolutions should allow for the feasibility of the proposed experiment.
