By faraday’s law, if a conducting wire of length ℓ meters moves at velocity v m/s perpendicular to a magnetic field of strength b (in teslas), a voltage of size v = − b ℓ v is induced in the wire. assume that b = 2 and ℓ = 0.5 . calculate dv / dv . find the rate of change of v with respect to time t if v ( t ) = 4 t + 9
