Unipolar Induction - a Messy Corner of Electromagnetism
A Contribution for The Clean Up with Some Far-Reaching Consequences
Abstract
In the light of own measurements on a Faraday generator the well-known theories concerning Unipolar Induction and the Faraday paradox seem to be problematic. On the other hand, all results obtained here and all other processes described as paradox in connection with the Faraday generator can be explained without contradiction on the basis of the theory of Wilhelm Weber.References
