At the least it will be interesting to see the difference between a ferromagnetic and ferrimagnatic core

Still need a source for soft ferrite powder.
How about something like this.

Google for ferrite rods give big choice on dims and materials.

Reference as to what to look for.

When I was looking into ferrifluid, homemade stuff used waste from bin under grinder sifted to small particle size. Hot iron oxidizes real fast. Never tried it myself. Found a small bottle of ferrifluid for like $5 on Amazon. No harm in trying different stuff. I think those rods would be attractive due to density.
