Magnets is made of iron. Magnets are attracted to anything made out of iron.
Magnets are attracted to anything with iron in it. Rust is Iron Oxide, so yes!
you can use magnets to separate iron from sand.

They stick to other magnets or iron, cobalt and nickel.
What is special about iron filings? Anything with iron in it has this property... magnets are attracted to iron! Magnets do not attract sand. You can use a magnet to separate iron filings from sand.
Rare earth magnets are very powerful magnets which have no iron. Cobalt and nickel are also magnetic.
polar things that can attract iron
