The magnitude of the average emf induced N= 220 in the coil is 4.10347 X 10⁻⁴ v.
Assume ,
N = 220
Area = 13 . 2 cm²
t = 4. 60 x 10⁻² sec
B = 6. 50 X 10⁻⁵ T
( a )
∅initial = NBA cosθ
=220 X 6 . 50 x 10⁻⁵ x 13 . 2 x 10⁻⁴x cosθ
1.8876X 10⁻⁵ T.m²
∅After= NBAcosθ
=220 X 6.50 x 10⁻⁵ x 13.2x 10⁻⁴x cob 90
( b )
∈=|-Δ∅B/Δt|
=1.8876 * 10⁻⁵/4. 60 x 10⁻²
=4.10347 X 10⁻⁴ v
