Question

What is an example of statically induced EMF?

Answer 1

Two faraday's laws are:

1. Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. If the conductor circuit is closed, a current is induced, which is called induced current.
2. The induced emf in a coil is equal to the rate of change of flux linkage.
3. From Faraday's law, we know that an EMF is induced in a coil when the magnetic flux through the coil is changing.
4. The induced emf in a coil is equal to the rate of change of flux linkage.$\begin{array}{l}E=N\frac{d\varphi }{dt}\end{array}$
5. Considering Lenz’s law,$\begin{array}{l}E=-N\frac{d\varphi }{dt}\end{array}$
6. When the conductor is static but the magnetic field is changing then an induced emf will occur, this is known as statically induced emf.
7. The transformer works on the principle of Faraday's law of electromagnetic induction and mutual induction.
8. Transformer is an example of statically induced EMF.
