Amagnetic b field of strength 18 t is perpendicular to a conducting loop of wire measuring 0.9 square meters with 30 turns. if the b field is linearly reduced to zero in 4 s, then what is the magnitude of the induced emf voltage? (in units of v).

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 =   ......1

magnitude of the induced emf voltage =

magnitude of the induced emf voltage =

magnitude of the induced emf voltage = 121.5 V

Beat frequency=f2-f1 (f2>f1)

Beat frequency=332Hz-300Hz=2Hz
