a compass always points towards the north, the brass rod doesnt make a difference.

no iron is a soft magnetic material. it loses its magnetism easily.
steel can be used to create permanent magnets.

So I still don't get it. For induced magnetism, can a hard magnetic material (eg steel) be magnetised when a manget is brought near it? Does it lose magentism when magnet is taken away?
