Question

The EMF induced in a conductor is?

Answer 1

EMF:

1. The electric potential produced by an electrochemical cell or by changing the magnetic field is referred to as electromotive force (EMF).

Induced EMF:

1. When the flux linking a conductor or coil changes, an EMF is induced.
2. The induced EMF magnitude, $\left|E\right|=\frac{d\varphi }{dt}$ where $\varphi$ is the magnetic flux.
3. So, according to the above formula, the induced EMF is directly proportional to the rate of change of electric flux.

Thus, The EMF induced in a conductor is directly proportional to the rate of change of electric flux.
