I am interested in conducting an experiment to prove or disprove the unusual qualities cited by many concerning the Faraday Disk generator.
I have read from several different sources (some bias and others non bias) that an induced EMF can be measured while rotating an induction disk inside a uniform magnetic field. For obvious reasons this struck me as odd. I am by no means an engineering genius but I do know the basics of electromagnetic induction and one of the basic tenants as taught by current textbooks is that you need a “changing” magnetic field to induce an electrical current.
The experiments intent is to explore the various methods that Faraday himself explored to induce an electrical current. I have read his notes and am confident I can reproduce his experiments with relative ease. I however will have more modern instruments and the benefit of a hundred years of accumulated knowledge to refer to with my findings.
I will conduct experiments on just 2 of the configurations he experimented with. One where being the induction magnet and disk are separated and only the induction disk is put into axial motion and the second will be where the magnet and copper disk are fixed together with an adhesive.
The purpose of the experiment will be to test for input/output efficiency. How much power (not energy) is required to drive the generator compared to how much power is produced. I intend to measure the circuit at full load to establish the constant for the experiment. I feel by placing 100% load on the circuit I can test the other variables such as rotor RPM and power output. This is where I need some advice from those of you who have the education and experience in this area that I lack.
I am interested in the community’s opinions and suggestions concerning this effort. I am also interested in your opinions with regard to the expected out come of my experiment. Please feel free to offer any constructive criticisms or advice you may have.
Also I hope this is the appropriate forum for this post.
