The Faraday paradox or Faraday's paradox is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes: Faraday's law appears to predict that there will be zero electromotive force (EMF) but there is a non-zero EMF.
Faraday paradox: An apparent violation of Faraday's law of electromagnetic induction. Two capacitor paradox : an apparent violation of energy of an electric circuit composed of two ideal capacitors Quantum mechanics
In his study on the subject, Carl Hering concluded in 1908 that the usual statement of Faraday's Law (at the turn of the century) was imperfect and that it required to be modified in order to become universal. [1] Since then, Hering's paradox has been used repeatedly in physics didactics to demonstrate the application of Faraday's Law of ...
The source free equations can be written by the action of the exterior derivative on this 2-form. But for the equations with source terms ( Gauss's law and the Ampère-Maxwell equation ), the Hodge dual of this 2-form is needed.
The Faraday paradox was a once inexplicable aspect of the reaction between nitric acid and steel. Around 1830, the English scientist Michael Faraday found that diluted nitric acid would attack steel, but concentrated nitric acid would not. [1] The attempt to explain this discovery led to advances in electrochemistry.
See Figure 1. To simplify, let the magnetic field point in the z-direction and vary with location x, and let the conductor translate in the positive x-direction with velocity v. Consequently, in the magnet frame where the conductor is moving, the Lorentz force points in the negative y-direction, perpendicular to both the velocity, and the B-field.
Another is overpotential, the difference between the theoretical and actual electrode voltages needed to drive the reaction at the desired rate. Even a rechargeable battery with 100% faradaic efficiency requires charging at a higher voltage than it produces during discharge, so its overall energy efficiency is the product of voltage efficiency ...
