1. The problem statement, all variables and given/known data Consider two straight conductors of length 1 m, each of them carrying a current of I = 2 A. If they are placed 1 m apart, what is the magnitude and direction of the force between these two conductors if there currents are a) in the same direction; b) in the opposite direction. 2. Relevant equations I know that B = [tex]\mu[/tex]0*I/2[tex]\pi[/tex]r I also know that that force on a conductor in general is F = ILBsin[tex]\theta[/tex]. 3. The attempt at a solution I calculated the magnitude of B according to the equation above and got 3.95-5 T. I'm not sure how to find the force of TWO conductors together though. Would you just do F = ILB for both conductors, adding the two F values of they are going in the same direction and subtracting if they are going in opposite directions? Is the direction determined by the RHR? Any insight would be much appreciated. Thanks!
