Chapter 29, Problem 022 GO Figure (a) shows, in cross section, two long, parallel wires carrying current and separated by distance L. The ratio iliz of their currents is 4.90; the directions of the currents are not indicated. Figure (b) shows the y component B, of their net magnetic field along the x axis to the right of wire 2. The vertical scale is set by Bys = 6.9 nT, and the horizontal scale is set by x, = 21.3 cm. (a) At what value of x > 0 is B, maximum? (b) If iz = 3.30 mA, what is the value of that maximum? What is the direction (into or out of the page) of (c) i, and (d) iz? Bys -Bys x (cm) (b) (a) (Lu) 7

A long straight wire carries 4A out of the page as pictured. A -10 µC particle, 2cm away from the current, travels upwards at a speed v = 2x106 m/s. (a) Calculate the magnetic field B, in components, at the location of the charge. (b) Calculate the magnetic force (vector) on the particle. a W
