Ferro-fluid sculpture

Here there are two metal cones standing in a pool of ferro-fluid. Each cone has an electromagnet under it, to create a variable magnetic field.

Wow!! Fascinating. Do you think the music is controlling the electromagnet? Or was the music composed for the nano dancers?

I don’t think there is anything so simple going on as hooking up the speaker wires to the electromagnet under the cone. I suspect that it is difficult to apply enough power to make the liquid move quickly without pulling the nano-particles out through the surface.

I guess you don’t want to mainline that stuff right before your next MRI.
Might be interesting, tho.

You could embalm a pig and send it through first to see what happens. I understood that the prohibition against metals had more to do with the damage done to the machinery rather than to the patient.

Good idea with the pig. I was curious about the MRI, so I found some safety information here:
There does seem to be some concern about patients.
The issue with the machine seems not to be physical damage, but rather downtime and recalibration (leading to lost revenue).
