Form1 1. Two magnetic dipoles are located on the y- axis, as shown. One dipole, A µ G , is located at the origin and its dipole moment is oriented along the + x axis. A second dipole, B µ G , is located at the dot. (The dot represents the position of B µ G , not its orientation.) What orientation of the second dipole, B µ G , will have the highest potential energy ? A. B µ G along the – y axis B. B µ G into the page C. B µ G along the + x axis D. B µ G along the + y axis E. B µ G along the – x axis

### 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.
