Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Permittivity & Permeability. The basic difference between permittivity and permeability is that calculates the hindrance offered by the substance in the creation of an electric field. While permeability explains the capability of substance that permits to flow of magnetic field lines in the material. On the polarisation of substance, permeability depends on magnetism.
In today’s post, we will have a detailed look at both permittivity and permeability with the details and compare them to find their differences. So let’s get started with the Difference Between Permittivity & Permeability.
Difference Between Permittivity & Permeability
Permittivity
- It is the behavior that shows the polarizing feature of any dielectric material
- The material that has a high value of permittivity is more polar and give a good response to the field given
- Permittivity is a factor that helps to measure the value of capacitance of any capacity
- It is denoted with the ε.
- Its mathematical expression can be formed by the ratio between displacement field strength and electric field strength.
- The system’s international unit of permittivity is Faraday/meter. and C/V.m
- The phenomena of permittivity is used in a capacitor.
- Its physical dependency is on Polarization.
- The value of free space permittivity is 8.85 F/m.
- the permittivity of material for space is called relative permittivity denoted as εr and also called the dielectric constant of that material
Permeability
- The ability of any substance that explains the movement of magnetic field lines in that material is called permeability.
- It is denoted with the μ.
- Its mathematical expression can be given by taking the ratio between magnetic field density and magnetic field strength.
- Its system international unit is Henry/meter. also measured in newton per amper square
- It used in the Transformer core to study the flux behavior
- The first time it was introduced by the Oliver Heaviside
- Its inverse is called reluctivity
- Its constant called magnetic contact used for the permeability of free space.
- The related term of permeability ions magnetic susceptibility
- phenomenon is based on Magnetization.
- The value of permeability of free space is 1.26 H/m.
- The field is generated by the material due to diamagnetism when the outer field is linked to it.
- Such material has a permeability value of less than one
- Material having permeability value larger than one called diamagnet
Permittivity vs Permeability
Permittivity
- The measuring of electric polarization of insulating or dielectric material when faces an electric field is called permittivity.
- It is denoted with the Greek letter epsilon (ε).
- Permittivity in terms of physics is the material ability to electrically polarize when an electric field is applied.
- dielectric medium permitviity is ε=εoεrε=εoεr
- Its System international unit is Farad per meter (F/m).
- It has two types relative permittivity (εr) and absolute permittivity (ε).
- It is a feature of material based on an electric field
- Free space permittivity is 8.85 × 10−12 F/m.
Permeability
- It is a feature or property of magnetic material that helps the flow of flux
- Denoted by the Greek letter mu (μ).
- The basic mean of permeability is the features of the material used for magnetizing due to magnetic field application.
- magnetic material permeability is μ=μoμrμ=μoμr
- The system international unit is Henry per meter (H/m)
- The permeability of free space or vacuum is 4π× 10−7H/m.
Is permittivity and permeability the same?
- Permittivity is a feature related to the production of an electric field and permeability is defined as the production of a magnetic field.
What is permeability also known as?
- magnetic conductivity.
What are the 3 types of permeability?
- Effective Permeability.
- Absolute Permeability.
- Relative Permeability.
What is permeability vs permittivity water?
- permittivity is volumetric flow in the cross-section of martial. Permeability is an advanced type of water in conjunction with thickness.
What is the SI unit for permeability?
- It is a proportionality constant that exists between magnetic flux density and magnetic field intensity. SI unit of permeability is Henry/meter
What is an example of permittivity?
- The capacitor comes with 2 charged plates separated from any insulation. One plate is a positive charge and the other is a negative charge. It produces electric field through insulated material between them
