How does the relative permeability of a ferromagnetic material vary with magnetomotive force?

There are a lot of subtle things associated with the answer to this question, but it might be best to answer by saying that with increasing magneto-motive force (MMF), the permeability of the material doesn't really change that much until the magnetic saturation of the material is approached.

What is geochemical mobility?
the ease with which it may be dispessed relative to the matrix of material sorrounding it
What is the main purpose of both relative dating and rediometric dating?
The purpose is to estimate or find the age of a material, or fossil.
What kind of conditions in terms of temperature and humidity are ideal for spray painting a wood material?
The conditions ideal for spray painting a wood material are a relative humidity of 55 percent and temperature of 20 degrees Celsius.
What kind of material is found in the MIDDLE mantle?
The middle mantle is made up of silicate rocks that are rich in iron and magnesium relative to the overlying crust.
Are only sedimentary rocks used for relative age determination?
No, igneous rocks can be used in this way based on the fact that an igneous intrusion will be younger than the material through which it passes. This is part of the principle of cross cutting relationships.
What material has a relative permeability of one?
vacuum
What is the numerical value of the actual mks permeability of the core material?
µr= relative permeability; µ=material of interest; µo= actual permeability µr=µ/µo
A magnetic material has a relative permeability of 10000 what does this mean?
The relative permeability of 10,000 means that the material can support a magnetic field 10,000 times more dense than than a magnetic field in free space.
Unit of relative permeability?
Relative permeability is dimensionless
What is dk measurement?
DK measurement is the measurement of the relative dielectric constant of liquids and solid material. It is a measure of permeability.
What is Relative Permeability of stainless steel?
The Relative Permeability of stainless steel is approximately 1. This is applicable to stainless steel with no or hardly any magnetic property.
What is end-point scaling in reservoir simulation?

What is the relationship between magnet length in the permanent magnet length and the flux density?
Magnetic flux density = mu x magnetizing intensity. ie B = mu H. mu is known as magnetic permeability of the medium. If it is just air or vacuum, then mu is mu0 ie permeability of free space whose value is 4pi x 10 -7 H/m. If it is other than air or vacuum then the permeability will be mur mu0 where mur is known as relative permeability. If mur is less than one then the magnetic material will be dia magnetic. If mur is slightly greater than one then magnetic material is para magnetic. If mur is very much greater than one then magnetic material is ferro magnetic.
What are two ways of making electromagnets stronger?
1. By increasing the number of turns of coil wound 2. BY using cores B = Ur Uo n I Here magnetic induction B is equated to relative magnetic permeability Ur of the core material and Uo the magnetic permeability of free space. N- the number of turns on the coil and I the current passing
What determines if a material will float in another?
Relative density.
What is geochemical mobility?
the ease with which it may be dispessed relative to the matrix of material sorrounding it
What is the difference between density and relative density?
Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.
