Abstract
A modified version of Faraday's unipolar inductor is presented. A special circuit is employed to reveal the portion of the circuit which has the seat of the unipolar induced emf. Historical questions concerning unipolar induction are thereby finally answered here: 1) The magnetic field lines do not rotate when a magnet is rotated. 2) Relative motion of the rotating disk and magnet is not essential to induce an emf. 3) Maxwell's flux rule is not always applicable.
