Question

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=−Blv is induced in the wire. Assume that B=2 and l=0.7.

Find the rate of change dVdv.

Answer 1

dV/dv = -Bl = -2(0.7) = -1.4
