1 . [1 point, 10 tries] Consider the current-carrying loop shown in the figure, formed of radial lines and segments of circles whose center are at point P. Assume that a=2.32 m, b=4.64 m and I=3.27 A. Find the magnitude of B at P. Answer: 7.38e-08 T 7 2 . [1 point, 10 tries] Three long, parallel conductors carry currents of I = 2.16 A. The figure below is an end view of the conductors, with each current coming out of the page. If a = 1.48 cm, determine the magnitude of the magnetic field at point A . Answer: 3.89E-05 T 7 3 . [1 point, 10 tries] Determine the magnitude of the magnetic field at point B . Answer: 1.46E-05 T 7 4 . [1 point, 10 tries] Determine the magnitude of the magnetic field at point C . Answer: 0.00E+00 T 7
