Exam 3Leview Name MULTIPLE CHOICE. Choose the one alternative that best com pletes the statement or answers the question 1) A cube 1.20 m on each side is oriented with one of its faces perpendicular to a magnetic field. The net magnetic flux passing through this cube is closest to: uniform 1.50-T 1) 0.00 Wb B) 13.0 Wb C) 4.32 Wt D) 8.64 Wb E) 2.16 Wb Figure 27.2 B = 0.80 T A uniform magnetic field of magnitude 0.80 T in the negative z-direction is present in a region of space. A uniform electric field is also present.

Explanation / Answer

Magnetic flux associated with cube is Zero. Since flux associated with surface is no. of field line leaving surface normaly. For cube if flux leaves one surface it enter to another surface. So it is positive for one surface and negative for opposite face and hence total flux is zero.
