Answer:
magnitude of the induced emf voltage = 121.5 V
Step-by-step explanation:
given data
magnetic field of strength B = 18 T
area = 0.9 m²
no of turn = 30 turns
Δt = 4s
to find out
magnitude of the induced emf voltage
solution
we get her magnitude of the induced emf voltage that is express as
magnitude of the induced emf voltage =
......1
magnitude of the induced emf voltage =

magnitude of the induced emf voltage =

magnitude of the induced emf voltage = 121.5 V
