Abstract
The Faradayan hypothesis of inductive coupling of the electromagnetic and gravitational fields is briefly discussed. An experiment designed to test the hypothesis wherein samples are spun to see if any electrogravitational charge is induced is described. Results of the experiment are reported. They imply the induction of a charge density ρ* for spinning samples that behaves as ρ*=βρma, where ρm is the mass density of an element of matter experiencing an acceleration a, and β is the coupling coefficient for the hypothetical electrogravitational induction effect. In this experiment, β is found to have the value(9.6±3.3)×10 −13 statcoulombs/dyne. Tests that seem to rule out explanations of the observed charges in terms of conventional charging mechanisms are considered.
