Electromagnetic Induction


Peer Evaluation



When there is a change in the magnetic flux linking a conductor, an electromotive force (e.m.f.) is induced between the ends of the conductor. This is called electromagnetic induction. If the conductor forms part of a circuit, the induced e.m.f. produces an induced current.




What are magnetic flux? Magnetic flux is simply a quantity of magnetic field passing through a certain area, it is the product of the average magnetic field and the

perpendicular area that it penetrates.
