Answer:
A mixture
Explanation:
The substance whose magnetic properties is tested is mixture of many compounds, elements or molecules.
A mixture has the following properties:
- Their composition is indefinite
- Their constituents retain their identity
- Constituents react differently to changed conditions
- Their constituent can easily be separated by physical procedures.
Since a part of the mixture responds differently to magnetism, we can say, the other part is made up of a different set of compound.
