Ferrofluid in a tipped over beaker being drawn upwards towards a magnet held behind. This video is at 1/20th speed and shows the complicated interactions between magnetic attractions, gravity and viscous forces.

Super cool fluid experiment! Bravo
The flow in this video is very interesting, and shows an interesting combination of forces acting on the fluid. The focus however does seem a little off so the image is somewhat fuzzy.
I like the phenomenon of the gravity acting along with the magnetic field
I like how you can see the fluid moving up towards the magnet
Its really interesting how you recorded a unique movement within in the magnetized fluoride. I am curious to known how the magnetic field created/interacted with this movement.
I like the colors you were able to capture, and how you captured the fluid moving upwards from the bottom of the beaker into the swirl.
Even though the video isn’t slow enough to capture the swirls 100% I think you still captured it well enough to convey the physics of the flow. Well done!
It’s very interesting to watch how it naturally swirls around in the beaker. Interesting concept and idea!
Pretty cool video, it’s fascinating to see how the ferrofluid combines with itself.
