Answer:
Option (C)
Explanation:
Electromagnetic induction means generation of a current in a coil due to relative motion between the coil and the magnet.
Electromagnetics induction works on the faraday laws,which states that,
"The emf is produced due to the change in magnetic field i.e the changing of magnetic flux leads to produced an induced emf.
if N is the number of turns in a coil then mathematical statement of a faraday law is,
where is the flux.
