1. The problem statement, all variables and given/known data What is the force magnitude on the first, second, and third wires in the figure? 2. Relevant equations (μ0L I1 I2)/(2πd) μ0 = 1.2566*10-6 3. The attempt at a solution Substituting 0.5 as L, 0.02 as d and 10 as I1 and I2 I get 5*10-4, which comes up as incorrect...what am I doing wrong? thanks!
