Answer to Question #231591 in Electricity and Magnetism for Zia

Question

DESCRIBE the following:

a)     Dynamically induced emf

b)     Mutually induced emf

c)     Self-induced emf and its method

Answer 1

a)Dynamically induced emf is an emf that has been induced into a conductor when conductor moves within the magnetic field. The magnetic field system needs to be kept fixed when the conductor moves so as to generate dynamically induced EMF

b) Mutually Induced emf is an emf induced into a coil because of to change in flux produced by the other neighbouring coil connected to it. ... The direction of the induced emf's direction is such that it tends to oppose the cause that produces it.

c) Self-induced emf tends to be the e.m.f induced in a coil because of change in flux that has been produced through connecting it with its turns.
