Consider two infinitively long, straight current-carrying wires, shown in Fig. 3.1. One wire carries a current of ly = 2.40 A in negative z direction; the other wire carries a current of 12 = 1.00 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 wires of current 13 = 2.00 A is placed at B and the direction of 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 to positive z direction with a speed v = 2.00 x 10 m/s, what is 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 cm is placed on yz surface with its center at 0, 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? If a third infinitively long, straight current-carrying wire with current 13 = 1.00 A in the native direction is introduced in Ein 21 whare.chard it honlend on the X Last saved 4:17:16 PM
