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.
What material should have high electro magnetic property?
Materials such as iron, cobalt, nickel, and certain alloys containing these elements are known for their high electromagnetic properties. These materials are often used in the production of magnets and electromagnetic devices due to their ability to retain magnetization effectively.
What is a material that freezes at a high temperature?
The freezing point of a material is the temperature at which the liquid phase turns into the solid phase.
What is a term used to describe a material that can be drawn into a long wire?
The term ductile would be applied to this physical characteristic of such a material.
A high explosive is a chemical material in which the process of decomposition proceeds through the material?
Yes, a high explosive is a chemical material where the decomposition process propagates through the material at a supersonic speed, creating a shockwave and releasing a large amount of energy rapidly. This rapid release of energy is what makes high explosives dangerous and suitable for use in military and industrial applications.
What materials are used to build a magnet?
Materials with high coercivity and high retentivity.

What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
Why should the material used for making permanent magnets have high coercivity?
High coercivity in permanent magnets ensures that they can maintain their magnetization in the presence of external magnetic fields, making them stable and reliable for long-term use. This property also allows the magnetic material to resist demagnetization, ensuring that the magnet retains its magnetic properties over time.
What metal has the lowest magnetic retentivity?
Generally, non-magnetic metals like aluminum and copper have low magnetic retentivity compared to magnetic materials like iron and nickel. They do not retain magnetism once a magnetic field is removed.
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.
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.
