What material have high retentivity?
steel
Why is soft iron named as soft iron?
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.
What is the composition of soft iron gasket material?
The soft iron gasket is pure iron with a carbon content of less tha 0.1 % . The hardness is Br<= 120
Can electro magnet magnetize and demagnetize soft iron?
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.
Why Soft Iron is suitable for preparing electromagnets?
soft iron B-H curve area is very high and hysteresis loss is proportional to it frequency or no of loop cycles per sec and area of loop so hysteresis loss increases in soft iron as electro magnet
What metal has the lowest magnetic retentivity?
iron
Differences between the magnetic properties of steel and iron?
Iron gets magnetized faster but loses its magnetism as soon as the inducing magnet is removed. Hence soft iron is said to have high susceptibility but low retentivity. This property of soft iron is very useful in making temporary electromagnets where we need strong but temporary magnets. If the magnets used in these devices were to retain their magnetism for a longer period, the devices would not function properly. Steel is slow to be magnetized but retains the acquired magnetism for a long time. Steel is said to have low susceptibility but high retentivity. Steel is used for making magnets.
Distinguish between the magnetic properties of iron and steel?
The magnetic properties of iron are high susceptibility and low retentivity. It means that it is easier to magnetize but also loses magnetism easily. The properties of steel are the opposite of iron.
What material have high retentivity?
steel
What three ways can you magnetize soft iron?
what are three methods of magnetising a piece of soft iron

Why is iron not as usefull as steel?
Iron is soft, and not as strong as steel.
What is the composition of soft iron gasket material?
The soft iron gasket is pure iron with a carbon content of less tha 0.1 % . The hardness is Br<= 120
If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
What is another word for soft iron?
what is another word for soft. Mild steel.
What materials are used to build a magnet?
Materials with high coercivity and high retentivity.
