Answer:
magnitude of the induced emf voltage = 121.5 V
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 = [tex]\frac{d\phi}{dt}[/tex] ......1
magnitude of the induced emf voltage = [tex]n*a * \frac{dB}{dt}[/tex]
magnitude of the induced emf voltage = [tex]30* 30* \frac{18}{4}[/tex]
magnitude of the induced emf voltage = 121.5 V
