MOST rocks are nonmagnetic. Rocks with a very high iron content will be magnetic. One type of rock, known as lodestone, IS a magnet.
Magnetic Earth rocks are those that contain magnetite.
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
There is nothing -_-
A common mineral present in magnetic rocks is magnetite (Fe3O4). It is a natural magnetic mineral that is attracted to magnets, giving the rock its magnetic properties. Magnetite is abundant in many igneous and metamorphic rocks, and is often found in beach sands and black sands.

rocks with magnetic fields that point south have
Moon rocks are very similar to earth rocks an they are not intrinsically magnetic.
yep
== == The most valuable rocks would be those partly comprised of the most valuable minerals such as gold, silver, and precious gemstones.

Rocks are valuable natural resource because we use rocks for lots of things like cement and brick like those stuff
The orientation of a rocks magnetic field can tell you it's relative age.
Although Lodestone is a naturally occurring magnetic rock, not all magnetic rocks are known as lodestone, and it is only magnetized because of the magnetite mineral in it.
magnetic fields
Many rocks have magnetic properties (are capable of being magnetized, are magnetic or are attracted by a magnet) derived from magnetic minerals in their composition like magnetite, hematite, and ilmenite. The most well known magnetic rock is the lodestone, which is comprised mainly of magnetite.
