Hemispherical Surface 001 10.0 points An open hemispherical surface of radius 0 . 1013 m is in a magnetic field of 0 . 158 T. The circular cross-section of the surface is perpendicular to the direction of the field. Calculate the magnetic flux through the surface. Correct answer: 0 . 00509361 T m 2 . Clockwise Current 002 10.0 points A circular coil of wire rests on your desk. A magnetic field is directed at right angles to the plane of your desk and passes through the coil. For a clockwise current (as you look down on your desk) to be generated, the magnetic field must be directed 1. downward toward the desk and be in- creasing in time. 2. upward away from the desk and be con- stant in time. 3. upward away from the desk and be in- creasing in time. correct 4. downward toward the desk and be con- stant in time.

### 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.
