Two parallel wires L_1 = 0.6m and L_2 = 0.6m carrying currents I_1 = 1.2A upward and I_2 = 3.6A downward, respectively. Calculate the force on wire 1 due to wire 2. Do the wires attract or repel each other?
Figure (a) shows, in cross section, two long, parallel wires carrying current and separated by distance L. The ratio i_1/i_2 of their currents is 5.10; the directions of the currents are not indicated. Figure (b) shows the y component B_y of their net magnetic field along the x axis to the right of wire 2. The vertical scale is set by B_ys = 5.8 nT, and the horizontal scale is set by x_s = 20.6 cm.

Three parallel current-carrying
wires are shown in the figure below. The currents in each wire are
I1 = 0.460 A, I2 = 0.710 A, and I3 = 0.260 A. If the wires are
separated by distances r1 = 0.185 m and r2 = 0.290 m, find the net
magnetic force per unit length on the middle wire due to the other
wires. (Express your answer in vector form.)
