Gravitational-Magnetic Field Interaction Proven with High-Voltage Capacitors Switch-On/Off and Rotating Superconductor

A transient force was observed with high-voltage capacitors switch-on/off by several teams with dozens of experiments. It is well-known that, in the maxwell equations, as an electric field is switched on/off, an instantaneous superstrong magnetic field can be produced. For the hypothesis of gravitational-magnetic field interaction, the superstrong magnetic field should make a transient variation of the gravitational acceleration. And, in another line, weight loss experiments with rotating superconductor in magnetic fields was observed by several teams. These experiments could be solid evidence for gravitational-magnetic field interaction. And, we presented that a large variation of gravity could be arrived at with superconductor.
