On second thought. I see what you mean and I got it backwards. You are applying a charge. I have you applying the magnetic field. Ostensibly they are equivalent but I can see where this might be considered not to be so.
How about this? Set up a little mini capacitor on a desk top made from just a couple pieces of aluminum foil. Place a coil , with a couple of wires attached to it along with a bar magnet inside the coil and place it flat on the table between the plates. Make sure the poles of the magnet face the plates. Charge up the capacitor a bit and then turn off the power source. Pull the magnet up by the wires until its perpendicular to the electric field. Attach the ends of the wire to a led and see if it lights. I'm definitely not an experimentalist but this seems like it should work.
An interesting idea, however: An LED would be a bad choice for a detector since it's threshold is 1.5 to 3 volts depending on the type used and will show nothing below that threshold, as there may be a pulse below this level that is missed. I would bet the signal from the coil is also dependent on the speed which the coil/magnet is turned perpendicular. Also what if the magnet / coil assembly were continuously rotated at some speed between the electric field plates. The signal could be brought out through slip rings for DC or rotary transformer if AC. Additionally the coil/magnet and capacitor plates would have to be magnetically shielded to prevent earth magnetic field from inducing a current into the coil. If you have a an idea, better to explain what you expect to see and why, then we can design a really good test experiment that subdues or ignores false positives. Better to use an oscilloscope or some DA instrumentation to record the low level output. We appreciate having those that can predict a possible outcome of an experiment, and there are also those here that love to design the experiments hardware / test setup. It is a synergistic combination for testing a hypothesis. Keep those ideas coming! Kind regards, ION
