Question:

http://web.ics.purdue.edu/~yeo/phys1.jpg [Broken]

Formula: (Gauss's Law for Magnetism)

Line integral of[B dot nhat(perpendicular unit vector) * deltaA] = 0

So, if there is a bar magnet inside, the side arrows are pointing in the wrong direction, so I ruled that out.

A magnetic monopole will have all arrows emanating from the center or all pointing towards the center, so I ruled that out.

The total flux is not 0, so there has to be

->That left me with only 2 other choices, but I've tried all combinations of them and none of them are correct. Any help guys? I only have 2 more tries left and its due tomorrow....

Thanks alot!
