Chapter , Problem 22(choose chapter or problem)
Figure 29-49a shows, in cross section, two long, parallel wires carrying current and separated by distance L. The ratio il/i2 of their currents is 4.00; the directions of the currents are not indicated. Figure 29-49b shows the y component By of their net magnetic field along the x axis to the right of wire 2. The vertical scale is set by Bys = 4.0 nT, and the horizontal scale is set by Xs = 20.0 cm. (a) At what value of x > 0 is By maximum? (b) If i2 = 3 rnA, what is the value of that maximum? What is the direction (irJto or out of the page) of (c) i1 and (d) i2
