## Homework Statement

This is the third part of a problem: The loop has a resistance of 0.20, an area of 200cm^2, and consists of 400 turns. What is the magnitude of the current in the loop at t=20s?

## Homework Equations

Magnetic Flux=BAcos(theta)

Faraday's Law=-N(Magnetic Flux)/time

## The Attempt at a Solution

I know I am missing an equation I need to figure this out but I'm not sure what it is. I have the N, A, t, and i have the resistance. I need to use the resistance to find the B, but I'm not sure how to do that. Please help. Thanks
