In a magnetic field with an induction of 0.5 T, a conductor 0.5 m long moves perpendicular to the induction

In a magnetic field with an induction of 0.5 T, a conductor 0.5 m long moves perpendicular to the induction lines at a speed of 4 m / s. What is the EMF of induction in a conductor?

Given:
B = 0.5 T
v = 4 m / s
l = 0.5 m
B⊥v
Find: E =?
Decision
Еi = -ΔФ / Δt
ΔФ = -BlvΔtsin (B; v)
Since the speed is perpendicular to the lines of magnetic induction, they form an angle of 90 °, therefore sin (B; v) = 1
ΔФ = -BlvΔt
Ei = BlvΔt / Δt = Blv
Ei = 0.5 T * 0.5 m * 4 m / s = 1 V
Answer: Ei = 1 V.
