1. The problem statement, all variables and given/known data It's Problem 6.6 on this page: http://web.ece.ucdavis.edu/~lxgliu/eec130a/2012winter/hw9s.pdf It has the solution and everything. I don't understand part (b) though. 2. Relevant equations 3. The attempt at a solution For part (b), I thought the direction of the induced current flow would flow as to oppose the change in the magnetic flux. The change in the magnetic flux here is dΦ/dt = -6.9sin(2πx10^4t) (V). They chose t = 0, but on an interval t =0 to say t = π/2, the sine function in the magnetic flux is greater than 0, which means dΦ/dt is negative and less than 0 right? Which in turn means the flux is decreasing. However, the flux is going INTO the page (-x direction) so shouldn't a decreasing flux mean it's getting less negative? So then the induced current I think should flow CLOCKWISE to oppose this change. This isn't what the solution says though, and I can't understand the way they did it. Can someone explain the fault in my reasoning?
