According to Faraday's law of electromagentic induction.
1 The direction of induced current is such that it opposes the cause producing it
2 The magnitude of induced e.m.f. produced in a coil is directly proportional to the rate of change of magnetic flux
3 The direction of induced e.m.f. is such that is fevar the cause producing it
4 None of the above
Explanation:
b \[ \mathrm{e}=\frac{-\mathrm{N} d \phi}{\mathrm{dt}} \]
