Document Summary

Please submit all completed work in hand-written form and show all work. B dl = 0 for a closed path of integration, which does not enclose the current carrying wire. Hint: consider the path of integration as shown in figure. 1; two segments of the path are parallel to lines of induction and two segments are perpendicular to lines of induction. (b) consider two parallel wires separated by a distance d and a point midway between the two wires. Figure 1: straight wire with current i into the page and eld b. Integration path is shown by the heavy lines. Figure 2: two parallel straight wires with current i out of the page. We are interested in the combined eld b at a distance r (cid:192) d. 2000 km (half-way between the inner core and the mantle) and with a current of.
