Are there any natural magnetic minerals?

This may shock you, but all matter is magnetic just to varying degrees. So yes there is. Here are the 4 levels of magnetic property's if you will. and examples of the minerals that have them.

Ferromagnetism - a strong attraction to magnetic fields. examples would be Magnetite and Pyrrhotite.

Paramagnetism - a weak attraction to magnetic fields. Example would be Platinum,

Diamagnetism. , Bismuth Is the only mineral that is diamagnetic, meaning it is repelled from magnetic fields.

Magnetism. Only a variety of one mineral acts as a magnet, generating magnetic fields on its own. This mineral is Lodestone, the magnetic variety of Magnetite, which found in only a few deposits throughout the world. Although it is only weakly magnetic, its magnetism is definitely discernible.
