WebMay 30, 2024 · The emf in a moving wire arises from the magnetic Lorentz forces acting on the free electrons, as they are carried along by the wire... F → = ( − e) w → × B → Here, w → is the velocity of the free electron. This is the vector sum of the wire's velocity, v →, and the drift velocity, v d r →, of the electron through the wire. So WebFaraday's law is a fundamental relationship which comes from Maxwell's equations.It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment. The induced emf in a coil is equal to the negative of the rate of change of magnetic flux times the number of turns in the coil. It involves the interaction of …
