1. The problem statement, all variables and given/known data A conducting loop with area 0.13m2 and resistance 6.0Ω lies in the x-y plane. A spatially uniform magnetic field points in the z direction. The field varies with time according to Bz=at2−b, where a = 2.8T/s2 and b = 8.0T . (a) Find the (magnitude of the) loop current when t = 1.3s. 2. Relevant equations V = I * R EMF = Δ(BA)/Δt * n 3. The attempt at a solution I calculated the EMF using the second formula listed, with n = 1 as there is only a single loop. EMF = Δ(BA)/Δt Binitial = 2.8(02) - 8 = -8 Bfinal = 2.8(1.32) - 8 = -3.268 => ΔB = 4.732 => Δ(BA) = 4.732 * 0.13 = 0.6152 => EMF = 0.6152 / 1.3 = 0.4732 V Then I used the first formula to find a value for I... 0.4372 = I * 6 0.0789 A = I This is incorrect however, and the correct answer given is 0.16 - roughly twice my solution. Am I leaving out a multiplier somewhere? Any help is appreciated, this seemingly simple problem has frustrated me for too long.
