Magnetic Earth rocks are those that contain magnetite.
Volcanic rock, especially basalt, contains some iron. When the rock is still molten the particles of iron are free to move, but are influenced by Earth's magnetic field. When the lava hardens into rock these iron particles are locked in place, essentially recording the orientation of Earth's magnetic field.
The magnetic dip preserved in a rock indicates the orientation of the Earth's magnetic field at the time the rock was formed. This information can be used to determine the past position of the rock relative to the magnetic poles and can provide insights into the Earth's changing magnetic field over time.
The first magnetic rock discovered is known as lodestone, a naturally magnetized form of the mineral magnetite. Lodestone has been used since ancient times for navigation and has played a significant role in the study of magnetism. Its magnetic properties arise from the alignment of iron oxide minerals within the rock.
Lodestone is a rock that has magnetic properties.
True. The magnetic orientation of a rock is locked in when the rock solidifies and cools below a certain temperature known as the Curie point. This is due to the alignment of magnetic minerals in the rock with the Earth's magnetic field at the time of solidification.
Magnetic rock is called Lodestone.

Magnetite.
As magma solidifies to form rock, iron-rich minerals in the magma align with Earth's magnetic field in the same way that a compass needle does. When the rock hardens, the magnetic orientation of the minerals becomes permanent. This residual magnetism of rock is called paleomagnetism.

Another word for magnetic rock is lodestone.
Magnetic orientation of rock refers to the alignment of magnetic minerals within the rock with the Earth's magnetic field at the time of formation. This alignment can provide information about the past magnetic field of the Earth and help in determining the rock's age and geological history.

mostly where i live; in texas ; because texas is so high in drout it makes the earth's magnetic feild harden :)
