Unformatted text preview: Jessica Ann Elrod- PHY 232 Spring 2007 1 Set 05 (02/20 midnight) Due date: Tue Feb 20 23:59:00 2007 A duck flying horizontally due north at 12.6 m/s passes over Atlanta, where the magnetic field of the Earth is 4 . 37 × 10- 5 T in a direction 59.3 ◦ below a horizontal line running north and south. The duck has a positive charge of 6 . 45 × 10- 8 C. What is the magnetic force acting on the duck? Tries 0/12 A wire carries a current of 11.7 A in a direction that makes an angle of 30.6 ◦ with the direction of a magnetic field of 0.333 T. Calculate the magnetic force on a 4.80 m length of the wire. Tries 0/12 A thin, horizontal copper rod is 1.44 m long and has a mass of 209 g. What is the minimum current in the rod that can cause it to float in a horizontal magnetic field of 0.742 T? Tries 0/12 A 5-turn coil encloses an elliptical area having a major axis of L = 40.9 cm and a minor axis of W = 28.3 cm, as seen in the figure. The coil lies in the plane of the page and has an I = 5.12 A current flowing clockwise in it. If the coil is in a uniform magnetic field of B = 1 . 70 × 10- 4 T, directed toward the left of the page, what is the magnitude of the torque on the coil?...
