What is the role of a magnet in separating mixtures?

• A magnet can be used to attract magnetic materials, such as iron filings, from a mixture, allowing for easy separation.

• A magnet can be used to heat up the mixture, causing components to separate based on boiling points.

• A magnet can be used to dissolve non-magnetic materials in a solvent, facilitating separation.

• A magnet can be used to change the color of the mixture, making it easier to identify components.
