Good observation, it also looks (if you look at the out of focus part at bottom) like the powder is "turning" to the right, it is far from conclusive though. I will get the magnetic film and do the experiment again.Tom.G said:The images from posts 92 & 93 (repeated here) suggest the magnetic field is perpendicular to the surface. That is also compatible with the magnetic compass pointing differently on the two surfaces of the disk.
You might get some magnetic field imaging film...
It seems that the strongest magnetic force is at the edge, when I moved the compass closer to the axis it seemed to loose it's "grip", however it does not mean that there is no magnetic field on the inside, it may just mean that the field is weak on the inside of the periphery and strong just at the edge where it completes its loop. One thing that is conclusive is that the compass is showing two poles.
