Query: Behavior of Electric Current Subjected to ELF Electromagnetic Radiation   Gravitational effects produced by ELF electromagnetic radiation upon the
electric current in a conductor are studied. An apparatus has been constructed
to test the behavior of current subjected to ELF radiation. The experimental
results are in agreement with theoretical predictions and show that ELF
radiation can cause transitory interruptions in electric current conduction.
