Proposal for Laboratory Generated Gravitomagnetic Field Measurement

Abstract

A method is described for creating a measurable unbalanced gravitational acceleration using a gravitomagnetic field surrounding a superconducting magnetic energy storage (SMES) toroid. When Forward (1962) first proposed a gravitomagnetic toroid for unbalanced force production any experimental realization was quite impractical. However recent advances in nanorod superconducting wire (nanowire) technology, described by Rieken (2018), has enabled a new class of SMES devices operating at current densities and magnetic field strengths sufficient to develop measurable gravitomagnetic fields, while still maintaining mechanical integrity. In the present paper an experimental SMES toroid configuration is proposed that uses an absolute quantum gravimeter to measure acceleration fields along the axis of symmetry of a toroidal coil, thus providing experimental confirmation of the additive nature of the gravitomagnetic fields, as well as the production of a linear component of the overall acceleration field.
