Unipolar Induction Revisited: New Experiments and the “Edge Effect” Theory


A brief historical review is made of the 180-year-old debate on Faraday's unipolar inductor. By introducing two convenient modifications of Faraday's original experiment of 1832, pertinent answers are experimentally found to the most debated problems: 1) Can Faraday's law be used? Yes; 2) Do the magnetic field lines rotate when the magnet rotates? No. 3… (More)
