The objective of this paper is to determine which postulates on the velocity of light and the force between moving charges are necessary to explain unipolar induction. A major experiment which can not be explained by Maxwell's equations is the unipolar generator which is a metal disc rotating in the fields produced by a permanent magnet or a current carrying conductor. A voltage is induced between the center and the edge of the rotating metal disc which is proportional to the angular velocity. This paper will compare the predictions of the New Gaussian and the Classical equations for the force between moving charges with experimental measurements. Only the New Gaussian equation correctly predicts the emf that was first observed by Faraday in 1831.
