I recently learned about faraday's law about electromagnetic induction , where you move a piece of magnetic towards and away from a coil of conductor, what if we replaced the magnet with an electret ( electrostatic equivalent to permanent magnet) and we moved it towards and away from a grounded metal disk , there will be current in the wire we used to ground the disk , is there any formula to calculate this current ??
why no one on the internet is mentioning this , except for 1 invention by tesla , which is basically a generator but instead of using magnets he's using plates charge by a wimshurst machine , and the current was produced by the repulsion/attraction between the electrons and the charged plates
