1. The problem statement, all variables and given/known data Three long parallel wires are 3.8 cm from one another. (Looking along them, they are at three corners of an equilateral triangle.) The current in each wire is 5.30 A , but its direction in wire M is opposite to that in wires N and P (see the figure). 1. Determine the magnitude of the magnetic force per unit length on wire M due to the other two. 2. Determine the angle of the magnetic force per unit length on wire M due to the other two. 2. Relevant equations F = μI1I2/ 2∏d 3. The attempt at a solution 1. F = (1.256*10^-6 NA^-2)(5.30 A)(5.30 A) / (2∏) (0.038 m) F = 1.474*10^-4 N 2. Does it make sense to you all if I used the fact: B = F / Il then did sin (F / Ilb) ^ -1 = θ for each wire, then take the summation of the θs?
