Fig. 28-4 shows three long, parallel, current-carrying wires. The current directions are indicated for currents I1 and I3. The arrow labeled F represents the magnetic force acting on current I3. The 3 currents have equal magnitudes. What is the direction of the current I2? vertical downward horizontal to the right out of the picture (in the same direction as I1 and I2) into the picture (in the direction opposite to that of I1 and I3) vertical upward
