Re: black sand why does it not go rusty from the salt

It is sometimes used in rust-proofing treatments for cars. I cannot be at all sure, but I suspect that your magnetic black sand is either the mineral magnetite, Fe3O4, or it is particles of iron coated with Fe3O4 and/or FeO. When I was about 10 or 11 I discovered that some black sand in our yard at home was magnetic.

Q A: magnets under water

The magnetic alignment energy is the product of the field and the magnetic moment of the magnet. The Earth's field is around a half a Gauss. That means that you need a magnetic moment of around 10-13 emu. A single electron can contribute about 10-20 emu. So you need about 10 7 electrons involved, at about one electron per atom for a typical

University of Minnesota's Mineral Pages: Hematite

Some hematite samples, however, do contain enough magnetite that they are weakly magnetic, so it is always a good idea to check a magnetic sample's streak by scratching the sample across a white ceramic plate. Hematite will leave a red to red-brown streak on the plate, while magnetite will leave a black streak. Ilmenite

why does dirt stick to magnets?

2006-2-13An easy answer would be to say that the soil you are using is rich in magnetic metals like iron. But in the United States, those soils are pretty limited. An acidic soil will leach minerals away, causing an excess concentration of metals, but these soils are only found in the coniferous forests of the very northeastern US and upper peninsula of
