    Emf Loop Wire
AI Thread Summary
An electromotive force (emf) can be induced in a coil of wire only when there is a change in the magnetic flux through the coil. Not all magnetic fields induce emf; it specifically requires a change. Inducing emf without a change in flux contradicts Faraday's law, which is a fundamental principle of electromagnetism. Faraday's law is part of Maxwell's equations and is crucial for understanding electromagnetic induction. The integral formulation of this law provides the necessary framework for these concepts.

an emf can be induced in a coil if the magnetic flux through the coil is changed my question is
does all magnetic field induces an emf in a loop of wire?

Hello Omar, ##\qquad## :welcome: ##\qquad## !

No, only change induces emf

another question Can we induce e.m.f. without any change in flux? Is it against Faraday's law?
