A square loop, 5.3 m on a side, is made of copper wire, 0.9 mm in radius. A 3.2 T magnetic field, perpindicular to the loop is increasing at the rate of 0.29 T/s. The resistivity of copper is 1.7 x 10^-8 ohm*m. Find the induced current. Answer in units of A.

2. Relevant equations

I'm assuming I need to use Faraday's law where I = V/R = magnetic flux/resistivity * time

3. The attempt at a solution

What actually threw me was the fact that the loop has a radius. So the area can't just be 5.3 squared and I dont think I need to calculate the area of a cylinder? Well I tried finding the initial value for the magnetic field then subtracting that from the final value after 1 second since it increases .29 T/s. I was just getting large answers and I can tell they would be somewhat large due to the large value of B, but I'm honestly stuck on how to set this beast up correctly.
