The Bitter magnets use massive amounts of power as well as water to cool them. Still if only 10 tesla is required for paramagnetic levitation and if the bore size is dropped to 3mm istead of 32 mm, I wonder how feasible this is on a home experimenters scale.
There needs to be a gradient of magnetic field as well which is sufficiently steep and with a stable centre. One end of a magnet would suffice rather than an iron cored bipolar magnet like my one described here.
Suspending a water droplet with a tiny tadpole may have to suffice though.
Maybe a few experiments on how much current can be put through a heavy wire under water flow before it disintegrates might be interesting as a start.
Cooling water flow. Hmmmm... Our pool pump is only a few feet away with a 1.5kW motor.
With the lack of a ferromagnetic core, running it through the can crusher setup would be feasible for a pulse of considerable power.

I am not thinking of modifying this coil or getting it wet. Heck I haven't even made it slightly warm yet. A new air cored coil with integral water flow is what I was thinking of with the working volume very small to still allow a lot of power in a small space. I dont have access to 6MW though. Sort of more like 5kW in a soft drink can size with high flow water through it and pushing the copper to the limit.
Just thinking about Ferrofluid. The spikes seem proportional to the field or field gradient - have to think about that one. Might be a handy way to record this directly although a hall effect device would be best if I can find one with the range.
