A conducting loop of face-area A and resistance R is placed perpendicular to a magnetic field B. The loop is withdrawn completely from the field. Find the charge which flows through any cross-section of the wire in the process. Note that it is independent of the shape of the loop as well as the way it is withdrawn.

Sol. Area = A, Resistance = R, B = Magnetic field
ϕ = BA = Ba cos 0° = BA
e = dϕ/dt = BA / 1 ; i = e/R = BA/R
ϕ = iT = BA/R
