So lets say that we have 2 wires that are parallel. To find the force that one exerts on the other I can use the equation B = μ0 I / (2 * π r), where μ0 is equal to 4(pi)e-7. But what can I do when I have 1 wire parallel to a wire that forms a loop. Will the equation still work?

2. Relevant equations

B = μ0 I / (2 * π r)

3. The attempt at a solution
