Static and dynamic induced emf
When the conductor is moved in a stationary magnetic field so that the magnetic flux linking with it changes in magnitude, as the conductor is subjected to a changing magnetic, therefore an EMF will be induced in it. The EMF induced in this way is known as dynamically induced EMF(as in a DC or AC … See more When a magnetic flux linking a conductor or coil changes, an electromotive force (EMF) is induced in the conductor or coil, is known as induced … See more When an EMF is induced in the coil due to the change of its own magnetic flux linked with it is known as self-induced EMF. Explanation − When a current flows in a coil, a magnetic field produced by this current through the … See more When the conductor is stationary and the magnetic field is changing, the induced EMF in such a way is known as statically induced EMF(as in a … See more When an EMF is induced in a coil due to changing magnetic flux of neighbouring coil is known as mutually induced EMF.
