Faraday's law of induction qânun-e darhazeš-e Faraday Fr.: loi d'induction de Faraday The induced → electromotive force in a circuit is equal in magnitude and opposite in sign to the rate of change of the → magnetic flux through the surface bounded by the circuit. Mathematically, it is expressed as: ∇ x E = -∂B/∂t, which is one of the four → Maxwell's equations. |
