What is meant by magnetic permeability?
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
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.
What does the term Nylon feet mean?
Nylon feet is referring to the lowest end of a nylon stocking. It covers the feet and also includes the legs with the nylon stocking. Nylon in of itself is a smooth type of material of which is sometimes associated with stockings.
How do you calculate speed of light in a vacuum?
-- look up the electrostatic permittivity of free space -- look up the magnetic permeability of free space -- multiply them -- take the square root of the product -- take the reciprocal of the square root The number you have is the speed of light in a vacuum.
Is nylon gasoline proof?

What is the magnetic permeability values of En8 steel and iron powder?
what is magnetic ppermeability of EN8
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.
The length of a part being magnetized by passing an electric current from one end to the other affect 1 permeability 2 strength of magnetic field 3 not affect magnetic field?
Permeability
What is permeability in electromagnetism?
Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself.(Degree of magnetization that a material obtains in response to an applied magnetic field.) It is represented by the Greek letter μ.
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 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.
How ferroelectrics are different from ordinary dielectrics?
ferroelectrics have strong magnetic field and also magnetic susceptibility & permeability value are strong (>1) but dielectric have feebly magnetic field & it have lesser value.
How does the permeability of a coil affect mutual inductance?
Since a coil contains numerous loops, more of the conductor is affectedÊ by the magnetic field. An increase in permeability of the core results in an increase in the inductance of the coil.
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 is true of any ferromagnetic materials?
It has an abnormally high magnetic permeability, it has a definite saturation point, and it has appreciable residual magnetism and hysteresis. That's why it remains magnetic even after the forcing magnetic field goes away.
What material should have high electro magnetic property?
A material with high initial permeability and low retentivity have electromagnetic property.
