Iron that has some carbon is cooled very rapidly from about 1300 degrees F. to close to room temperature . The carbon atoms get in the way of the iron atoms as they form a lattice work in the cooling steel. that makes the steel very hard but very brittle. The the next step is to reheat the iron to about 440 degrees F. that way you get a reasonably hard iron that won't break when you need to use it.
I assume you mean "soft iron" ... so that it quickly loses its magnetism when the current flow stops.
Soft iron does not retain magnetism. It can be magnetised and demagnetised quickly and easily. Used as a core for transformers. 'Soft' probably relates to it's submission, when exposed to magnetism. It 'gives in' without too much fuss.
Soft iron will not have any magnetic properties unless it is magnetized, while a piece of copper will not be attracted to a magnet at all. A magnet will attract both soft iron and copper, but the attraction will be stronger for the soft iron due to its ability to become magnetized.
Yes, they can magnetise soft iron. Not sure about demagnetising though. I assume that if more than one or two were placed around the soft magnet, it could demagnetise it.. However, the soft iron would need to be 'hit' so that the poles in the iron can allign with the magnetic fields due to the electro magnet.
Iron Brew is a carbonated soft drink that is flavored with fruit extracts and spices. It does not contain iron as the name may suggest, but is usually made from a combination of water, sugar, caffeine, flavoring agents, and coloring. Its exact recipe is a closely guarded secret by the manufacturer.
Pure iron is relatively soft and easily worked (malleable). Iron heated to high temperatures and alloyed with carbon and other elements is called steel, which can be made extremely hard and durable, but not easily worked.
it depends on what state it's in(:
That depends on what you mean - soft iron is usually the name given to iron that is easily magnetised and demagnetised. In which case it is usually very pure. Mecahnically soft and hard irons have different crystal structures and trace impurities, although iron is more correctly known as steel when it is anything but 100% pure iron.
Zinc is considered a hard metal; its hardness is similar to that of Iron.
soft balls are made when you get kicked in the balls hard and made with sperm
They are made both soft and hard, depending on application.
The difference is in the name; soft corals have a soft body, with no bony or hard parts. In contrast, hard corals have a hard endoskeleton made of calcium carbonate.
it is made up of gas so thhe answer is soft
A magnet is made of 'Soft' Iron. A pin has steel (iron) in it. A match does NOT have iron in it.
The Kurrajong tree is made of very soft wood.
The outer core of the Earth is actually liquid, made up of molten iron and nickel. This liquid layer is responsible for generating the Earth's magnetic field through convection currents.
Alkali earth metals are relatively soft compared to transition metals, like iron or copper. They can be cut with a knife due to their low hardness.
