1. The problem statement, all variables and given/known data A 21cm×21cm square loop has a resistance of 0.12 Ω . A magnetic field perpendicular to the loop is B=4t−2t^2, where B is in tesla and t is in seconds. (A) What is the current in the loop at t=0.0s? (B) What is the current in the loop at t=1.0s? 2. Relevant equations for a square loop, B = (√2)(μ_0*I)/(π*R), where R is the length of the side 3. The attempt at a solution (A) I assumed that at t = 0, B = 4(0) - 2(0^2) = 0. 0 = (√2)(μ_0*I)/(π*.21), but that means I = 0 A and that didn't work. Help please? Thanks.
