Cоnsider twо lоng strаight current-cаrrying pаrallel wires, shown in Fig. 3.1. One wire carries a current of I 1 = 1 . 50 A in negative z direction; the other wire carries a current of I 2 = 3 . 60 A in negative z direction. (a) Find the magnitude and direction of the net magnetic field at point A. (b) Find the magnitude and direction of the net magnetic field at point B. (c) If a long, straight current-carrying wire of current I 3 = 2 . 00 A is placed at B and the direction of the current in this wire is in positive z direction, what are the magnitude and direction of the net force per unit length on this wire? (d) If an electron passing point B is moving in positive z direction with a speed v → = 2 . 00 × 10 7 m / s , what are the magnitude and direction of the magnetic force on the electron? (The charge of an electron is - 1 . 60 × 10 - 19 C .) (e) If a single current-carrying loop of radius R = 2 . 00 c m is placed on y z surface with its center at O , as shown in Fig. 3.2, what is the magnitude and direction of the current in the loop if the magnetic field at its center is zero? fig_q13_t2.jpg
