Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0points A rectangular loop located a distance from a long wire carrying a current is shown in the figure. The wire is parallel to the longest side of the loop. 3 . 32 cm 7 . 52 cm 28 cm 0 . 0284 A Find the total magnetic flux through the loop. Answer in units of Wb. 002 10.0points A wire in the shape of an equilateral trian- gle 5 . 88 cm on a side is placed in a uniform magnetic field of magnitude 0 . 147 T. If the field makes an angle of 64 . 7 with the plane of the triangle, determine the magnetic flux through the triangle. Answer in units of T m 2 . 003 10.0points A coil is wrapped with 286 turns of wire on the perimeter of a square frame of sides 33 . 4 cm. Each turn has the same area, equal to that of the frame, and the total resistance of the coil is 2 . 46 Ω. A uniform magnetic field is turned on perpendicular to the plane of the coil.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
