03 Exercise 7 02 от OI Eight wires cut the page perpendicularly at the points shown in Fig. 15-42. A wire labeled with the integer k (k-1, 2, . . . , 8) carries the current k, ,where i- 4.50 mA. For those wires with odd k, the current is out of the page; for those with even k, it is into the page. Evaluate y B ds. along the closed path indicated and in the direction shown.
Chapter 29, Problem 011 In the figure, two long straight wires are perpendicular to the page and separated by distance di-0.75 cm. Wire 1 carries 7.0 A into the page. What are the (a) magnitude and (b) direction (into or out of the page) of the current in wire 2 if the net magnetic field due to the two currents is zero at point P located a distance d2 1.50 cm from wire 2? Wire 18 Wire 2O (a) Number...
Chapter 29, Problem 029 In the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a 19 cm. The currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3, and each wire carries 17 A. What is the magnitude of the net magnetic field at the square's center? Number Units Chapter 29, Problem 062 In the figure, current i-35.9...
Chapter 29, Problem 027 In the figure, two long straight wires (shown in cross section) carry currents i 23.8 mA and 12 -30.3 mA directly out of the screen. They are equal distances from the origin, where they set up a magnetic field B. To what value must current i1 be changed in order to rotate B 18.3° clockwise? Number Units the tolerance is +/-796
