ferrofluid

Playing with homemade ferrofluid. Refined from captured grinder sparks, and filtered by time and powerfull magnets through a multi-stage process lasting weeks. This primitive ferrofluid uses 90 weight gear oil as a medium to prevent settling.

The process used to create the fluid involved placing a catch basin under my grinder. Filling it with oil. Mixing the filings well. Using magnets to pull out large particles, then pouring off the oil. The remaining particles don't come out of solution easily, so the next stage lasts a couple of weeks. The magnets eventually pull the particles out of solution, and clean oil is poured back to the beginning stage. The particles left at the end of this process are small enough to stay suspended for a while, but mixing is needed periodically.

This video shows a little mixing during the final stage, then drops falling sideways toward the magnet.

@rguerzo the fluid itself is not magnetic.

Question! If you completely fill an air-tight cylindrical container with the magnetic fluid, will it react like a normal solid magnet having North and South Poles? How can we achieve it? I want to know please, Thanks.
