What material should have high electro magnetic property?
A material with high initial permeability and low retentivity have electromagnetic property.
Is a pyroclastic material high or low-viscosity?
Pyroclastic material can form with magma of any composition, but it is more likely to form with high-viscosity magma.
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?
faster than the speed of sound
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 material should have high electro magnetic property?
A material with high initial permeability and low retentivity have electromagnetic property.
Why should the material used for making permanent magnets have high coercivity?
The material should have high retentivity so that the magnet is strong and high coercivity so that the magnetisation is not erased by stray magnetic fields
What materials are used to build a magnet?
Materials with high coercivity and high retentivity.
What metal has the lowest magnetic retentivity?
iron
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.
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.
If a material has a high conductivity does it have a high permeability and if so what would be an approximate permeability for the high conductive material?
ni ata answer
What is a material that conducts current?
Material with high resistance
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.
What does a conventional bomb have in it?
high explosive material or incendiary material
What is a material that conducts electric current?
Material with high resistance
What is a material that conducts electric current slowly?
Material with high resistance
