The diagram shows four circular Amperian loops ( a , b , c , d ) and, in cross section, four long circular conductors (the shaded regions), all of which are concentric. Three of the conductors are hollow cylinders; the central conductor is a solid cylinder. The currents in the conductors are, from smallest radius to largest radius, 4 A out of the page, 9 A into the page, 5 A out of the page, and 3 A into the page. Rank the Amperian loops according to the magnitude of ∮ B → · d l → around each, greatest first. fig_q9_t2.jpg

Consider two long straight current-carrying parallel 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

Rank the following in order of their likely weight misconvergence error—the lowest error is 1 and the highest error is 7. In every case, there is the same amount of low-level noise added to the target signal d[n]. Also, assume that the system is stationary and that any parameters not specified below have been chosen to yield a reasonable trade-off between convergence speed and weight misconvergence. If one of the comparisons doesn’t yield a clear ordering in your opinion, explain your thinking in your uploaded notes.
