Answer:
THEORY
Explanation:
Naturally, all the minerals cannot be magnetized. In order to get magnetized, the mineral must contain iron oxides in it, that shows the magnetic property and this magnetism occurs due to the motion of electrons in its existing atomic structure. The most common mineral exhibiting magnetism is magnetite, that contains iron oxide in it.
The above given statement is considered to be a theory, because test an experiments were carried out long back, and it has been proved that minerals containing iron can only be magnetized. For example, Magnetite.
