I am making a visual display that functions with music and I am using ferrofluid, under which 30 electromagnets will be placed in a field.
Has anyone experimented with ferrofluid? What power ranges for the magnets would you recommend? I don't have much time for this project so experimenting is almost impossible, but I can a little bit if I have to. I am gonna order some ferrofluid for now, and then will make more of it when I need it (I will need around 7-8 gallons, which costs way too much)
I am planning the depth to be around 1 inch deep of ferrofluid. Which is probably important in figuring out the power of the magnet.
