Answer
given,
turns in coil (n) = 200 turns
area (A)= 12 cm²
time(t) = 0.040 s
electric magnetic field = 6 × 10⁻⁵ T
θ = 0°
a) total magnetic flux
∅ = n B A cos θ
∅ = 200 x 6 × 10⁻⁵ x 0.0012 x cos 0°
∅ = 1.44 × 10⁻⁵ Wb
b) average emf induced
[tex]E = \dfrac{d\phi }{dt}[/tex]
[tex]E = \dfrac{1.44 \times 10^{-6}}{0.040}[/tex]
[tex]E = 3.6 mV[/tex]
