Brandon Pope · Answer 1

Answer: A. It has opposing magnetic moments.

Explanation:

Magnetite, Fe3O4 is Ferrimagnetic and quite different from Ferromagnetic minerals because it's magnetic moments are aligned in opposite directions.

Addison Tanner · Answer 2

Option A

Explanation:

Ferromagnetic materials have the property to be attracted to magnets while ferrimagnetic material is the magnetic property of materials having atomic moments aligned in opposite directions. In ferrimagnetic material as the magnetic moments are aligned in opposite direction, they cancel out the magnetic field.
