Question

observer
2. The direction of the induced emf
during electromagnetic induction
is determined by
(a) Ampere's law (b) Lenz's law
(c) Faraday's law (d) Maxwell's law
​

Answer 1

Faraday's Law (Option c)

If the force finger points in the direction of the magnetic field, the thumb gives the direction of the motion of the conductor then the middle finger gives the direction of the induced current. From Faraday's law, induced e.m.f is given by E=−Ndϕdt.

Hope this helps!!

Mark as the brainlliest answer..
