Hematite can only obtain magnetism via antiferromagnetism, assosciated with a small net magnetisation allowed through crystal lattice defects.
By far the most important magnetic rocks are those containing magnetite. However the Ti-O-Fe solid solid solution all have ferrimagnetic properties (i.e. they retain magnetization).
Magnetite occurs in a range of rocks, including sandstones, granites and metamorphic rocks. However it is typically most concentrated in mafic, iron-rich rocks and sedimentary iron formations.
The only type of rock that sticks to a magnet is lodestone, also known as magnetite. Lodestone is a natural magnet due to its high iron content, which allows it to be attracted to magnets.

Why might a magnet that sticks to your refrigerator be unable to pick up a far away paper clip?
The magnetic force weakens with distance, so the magnet may be unable to exert enough force to pick up the paper clip when it is far away. The strength of the magnetic field decreases rapidly with distance, which is why the magnet can only attract objects that are close to it.
What is the name given to a natural magnet?
The natural magnet is present at the core of our planet earth.
Is slate rock attracted to magnet?
No, slate rock is typically not attracted to a magnet because it is composed mainly of minerals like clay and quartz, which are not magnetic. Magnetic properties in rocks are usually found in those containing iron minerals, such as magnetite.
Could glucose get separated from a magnet?
No, glucose is not magnetic and therefore cannot be separated from a magnet as magnets only attract materials that contain iron.
Is a magnet made of lodestone?
Yes, lodestone is a natural magnet made of magnetite ore. It is a naturally-occurring magnetic rock that can attract iron.
What sticks to a temporary magnet?
Anything that is attracted to a permanent magnet will be attracted to (sticks to) a temporary magnet.
What is a ring stamped with IM it is gold looking with a red stone and sticks to a magnet?
If it sticks to a magnet it's not gold.
Is real gold or silver that only has a small part that sticks to a magnet worth any money?
Yes it is
Where is the magnetic field on a magnet?
On the gray side of the magnet, if you take out a magnet and put it next to a magnet things you put on the fridge, It sticks to it! You see, the magnet's force is invisible so u can't see it. Or if you put it next to a magnet that sticks to that magnet, You might feel it's force or not. I tried it once :).
What is the word when a magnet sticks to the fridge?
magnitisim
How do you clear memory sticks?
use a magnet
Why don't magnets stick to magnets?
Magnet sticks to another magnet when north pole of the first magnet approaches the south pole of the second magnet.
How do you tell if its a magnet?
It is usually labelled 'magnet' Also, it sticks to stuff like, say, your fridge.
What best explains why a magnet sticks to a refrigerator?
A magnet sticks to a refrigerator because the refrigerator door is made of a ferromagnetic material, such as steel. The magnet and the refrigerator door have opposite magnetic poles, causing them to attract and stick together.
What happens when a magnet is flushed down toilet?
it sticks to the pipe
Do steel wire screen sticks to magnet?
Steel will stick to magnets, but stainless steel will not.
What makes a magnet stick to a refrigerator?
A magnet sticks to a refrigerator because the metal of the fridge is ferromagnetic, meaning it can be magnetized. When a magnet is pressed against the fridge, it creates a magnetic field that aligns with the refrigerator's magnetic field, causing the two to stick together.
