A loop of wire with radius r = 0.045 m is in a magnetic field with magnitude B as shown in the figure. B changes from B1 = 0.65 T to B2 = 1.5 T in Δt = 2.5 s at a constant rate. The resistance of the wire is R = 11 Ω. Express the magnitude of the average emf, ε, induced in the loop in terms of ΔΦ and Δt
