Ok, I need a lot of help on this one. A single conducting loop of wire has an area of 7.4*10^-2 m^2 and a resistance of 110 ohms. Perpendicular to the plane of the loop is a magnetic field of strength 0.18 T. At what rate (in T/s) must this field change if the induced current in the loop is to be 0.22 A? So far all I can figure out is that Phi=BA. And I don't think that has anything to do with this problem. :grumpy: Thanks for any and all help.
