The circuit is shown below: Find the current through section PQ of length a = 65.0cm. The circuit is located in a magnetic field whose magnitude varies with time according to the expression B = (1.00 x 10^-3T/s)t. Assume the resistance per length of the wire is 0.100 Ohm/meter.

---------2a--------Q-----a-----

The entire circuit is in a changing magnetic field that is going into the screen perpendicular to the plane of the circuit (nevermind the dashes between the 2a, Q, and a or the dots above and below the other a...they're just there for spacing).

I've tried several methods (actually, only 2 that I kept repeating, but they seemed right). The current along PQ should be found through finding the voltage between P and Q and using that (along with the resistance) to find the current. The actual answer is 283 x 10^-6A upward, but my answers dont match. Any help??
