How does soft iorn is different from hard iron?
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.
Is zinc soft?
Zinc is considered a hard metal; its hardness is similar to that of Iron.
Can soft iron be made from hard iron?
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.
What is soft iron hardness?
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.
Are alkali earth metals hard or soft?
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.
Why is soft material is preferred to make electomagnet than hard?
I assume you mean "soft iron" ... so that it quickly loses its magnetism when the current flow stops.
How do you distinguish between soft and hard metals sodium and iron?
Sodium is a soft metal that can be cut with a knife and has a low melting point, while iron is a hard metal that cannot be cut easily and has a higher melting point. Additionally, sodium is highly reactive with water, while iron is relatively less reactive.
What is the difference between soft and hard iron?
The essential difference between soft iron and hard iron is in the crystalline structure of the metals. This is sometimes due to the presence of impurities, but the over-riding effect is that of heat treatment. The basic techniques (for iron) are to get it white-hot, then cool it slowly; this produces soft iron. Alternatively, get it dull red, or bright red, or yellow, or white, then plunge it into cold liquid. This process, called quenching, hardens the iron. Picking the correct colour before quenching gives just the hardness needed.
What softwoods are hard?
All woods are hard but depending what your description what of hard is like rock can be really soft compared to iron and wool can be harder than a polyester fleece throw
Is brown soft or hard?
Hard
Is gold considered a soft metal or hard metal?
Gold is considered a relatively soft metal. It has a Mohs hardness of about 2.5 to 3, which means it can be scratched easily compared to harder metals like iron or steel.
How many is retentivity of soft iron?
Retentivity, or magnetic retentivity, refers to the ability of a material to retain magnetization after an external magnetic field is removed. For soft iron, the retentivity is relatively low compared to hard magnetic materials; it typically measures in the range of a few milliTesla. This property makes soft iron ideal for applications like electromagnets and transformers, where rapid magnetization and demagnetization are required.
