Lets say you have an old car with a rust problem in the gas tank. Has anyone ever tried to put a magnet on the bottom of the tank, to hopefully hold the rust particles out of suspension, and out of the filters?

Figure they're big enough to hold the rust in place.

We tested the dried residue, which was no longer magnetic. We then heated it in a spoon over a candle flame, which turned it black. It was magnetic again. What was the process that "remagnetized" it?

Your residue lost all water and a little oxygen and maybe also recrystallized while in the solid state, to a form more appropriate to its new composition.

If so some recrystallization should be able to occur on the molecular level, though perhaps not to crystals large enough to be visible. It is possible the gasses in the candle flame helped chemically, not just thermally, with some of the oxygen removal. If the flame wrapped around the spoon on all sides, it might create an oxygen-depleted or reducing atmosphere in the spoon.

Carbon monoxide, unburned wax fumes, and soot are all reducing agents for the conversion of Fe2O3 to Fe3O4. Joined: Feb 21, Posts: 2, Profile Page.

I routinely put magnets inside of gas tanks I use a stainless steel hose clamp to attach a copper wire so I can retrieve it and clean off the rust.

Also use a settlement bowl with a creamic filter between the gas tank and the fuel pump. Even by taking off a gas tank you cannott get to all of the area to clean it completly.
