I've been curious about the images of ferrocells posted on these forums. It appears to me that the bulk of the lines pass through the magnet perpendicular to the direction of the magnetic field (instead of North-South, East-West, so-to-speak). Upon further search, I came across this discussion:
the Ferrocell
Notice the green image. These microscopic lines or features form in the thin layer of ferrofluid perpendicular to the magnetic field. It may be responsible for the orientation of the reflected/refracted light captured by the camera. Interesting read.
I'm just trying to figure this out. It is obvious that we are seeing an effect from the magnet but I am far from convinced we see a representation of the magnetic field.
