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.
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.
How velocity of light is calculated?
The speed of light can be both calculated and measured. Light waves are formed by mutually interacting orthogonal electric and magnetic fields. Using properties of these electric and magnetic fields, you can arrange the equations of physics into a partial differential equation, called the "wave equation". This equation contains a constant in it, which is the wave-speed of light. It's value is found from other physical constants, and is about 3 106 km/sec. This value was measured in a vacuum and found to be within excellent agreement. James Clerk Maxwell first theoretically found the speed of light from what is now called the Maxwell equations.
What is the exact value of the speed of light in a vacuum?
The speed of light in a vacuum is 299 792 458 meters per second or 983,571,056.43045 feet per second or 186,282.397 miles per second or 670,616,629.2 miles per hour.
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.
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.
What is permeability value of germanium?
16.0 is the value of permeability
What material has a relative permeability of one?
vacuum
How is the speed of light generated and kept constant in a vacuum?
The speed of light is the result of the electrostatic and magnetic properties of the medium through which it's traveling. The speed changes when those properties change. In vacuum, the electrostatic permittivity and magnetic permeability of free space result in a speed of 299,792,458 meters per second.
What is the magnetic permeability values of En8 steel and iron powder?

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.
