The direction of induced current or the polarity of induced emf can be found by
The direction of induced current or the polarity of induced emf can be found by
Open in App
Solution
The correct option is C Lenz’s law
The direction of induced current is such that it opposes the change in magnetic flux through the loop. The current inside a battery goes from negative potential to positive potential so, the current direction can also give us the polarity of induced emf.
