Title: Ferrofluid Calligraphy
Post by: jellis1221 on November 21, 2015, 05:29:22 PM
Hello! I'm new to the forums and saw quite a few ferrofluid topics, but none could quite answer my question. (Hopefully this is posted in the right place.)

I'm working on an interactive electromagnetism project that will ideally allow users to "write" with ferrofluid. The goal is to be able to control ribbon-like ferrofluid strips. This video is my main inspiration. (

So my question is: how does this work? Specifically, what possible solvent is the fluid in the above video suspended in to achieve that effect?

As a disclaimer, my background is in art - with pretty much no chemistry training - but I'll do my best to explain things on my end.

Video observations:
Here's where I am so far with solvent testing. Note: the tests were performed in a plastic petri dish, and after dropping in 3-4 ferrofluid drops the mix was magnetized from the bottom.

Any suggestions will be helpful!
