my problem asks for magnitude.

oh yeah i was given 500cm^2 but that still converts to 0.05m^2 so it was just a slip of the hand, I still don't see what else is wrong.

I still don't get it. Is my math wrong?

Oh, I am not sure if I'm in the same class or not and my problem is that I DON'T know what the correct answer is BUT I do know mines is the wrong one. Thanks for the help let me think/try it now.

How do you solve for a? I did the following: induced emf e = - N dφ/dt flux φ = B * A ( A is the area of loop) e = - 1 * d( B * 0.5m^2 ) /dt -12 = - 0.05 * dB/dt dB/dt = 12/.05 = 240 T/s Why is this incorrect? It asks for magnitude so sign shouldn't matter anyways.

How should one go about solving f?

Would it be for the same concept for the diagram below?
