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.
What else can I help you with?
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.
Could glucose get separated from a magnet?
Glucose is not a metal and can not be separated using a magnet.
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.
Is a magnet made of lodestone?
a naturally occurring magnet composed of a form of iron called magnetite
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 :).
How do you clear memory sticks?
use a magnet
What is the word when a magnet sticks to the fridge?
magnitisim
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 is it called when iron sticks to a magnet?
When iron sticks to a magnet, it is referred to as magnetic attraction. This phenomenon occurs because iron is a ferromagnetic material, meaning it can be magnetized and is attracted to magnets. The magnetic field of the magnet aligns the magnetic domains in the iron, causing it to be pulled toward the magnet.
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.
