I would like to experiment with using a liquid that has similar non-linear properties to solid ferrite rod. The general idea is to immerse a coil in it.
Can anyone please offer suggestions on what would be the most suitable product/material?

I'm probably totally wrong but maybe ferrofluid???

I got a sample of ferrofluid at CES. Though well sealed, what was in the vial turned to a solid. I certainly hope that was a fluke.
??? Iron compounds like nitrates or clorides?? (wild guess)
Nope! Those are paramagnetic, in fact.
They have positive relative permeability, it's just really stinking low. :)

A suspension of powdered iron in glycerine?
Good Luck! Rich
ferrofluid???
Did you try degaussing it? ;-)
Cheers! Rich
Ferromagnetism is due to long-range order, only happens in solids, not liquids. Ferrofluids are suspensions of solid magnetic particles in a liquid. The difference will matter if high frequencies are present (the particles will rotate and dissipate energy).
Liquids can be highly paramagnetic, try liquid oxygen.
