Question

Look at the list of mixtures and select the ones that could be separated by magnetism. Check all that apply.

beach sand
nickel ore
trail mix
iron-fortified vitamins
freshly mined coal

Answer 1

The mixtures that could be separated by magnetism from your list are:

- **nickel ore** (if it contains magnetic nickel)
- **iron-fortified vitamins** (if they contain iron, which is magnetic)

The other mixtures, such as beach sand, trail mix, and freshly mined coal, do not generally contain ferromagnetic materials that would be attracted to a magnet. Thus, the applicable items for separation by magnetism are nickel ore and iron-fortified vitamins.
