Two very long, parallel wires are separated by d = 0.035 m. The first wire carries a current of I1 = 0.65 A. The second wire carries a current of I2 = 0.45 A. Part (a) Express the magnitude of the force between the wires per unit length, f, in terms of I1, I2, and d. Part (b) Calculate the numerical value of f in N/m. Part (c) Is the force repulsive or attractive? Part (d) Express the minimal work per unit length needed to separate the two wires from d to 2d. Part (e) Calculate the numerical value of w in J/m.
