Is there a difference between the terms permeability and permitivity used in magnetism and electrostatics.?

Permeability

1) the passage or diffusion (or rate of passage) of a gas, vapor, liquid, or solid through a barrier without physically or chemically affecting it. 2) the ability of a material to carry magnetism as compared to air which has a permeability of 1

Permittivity

preferred term for dielectric constant. It is that property of a dielectric material that determines how much electrostatic energy can be stored per unit of volume when unit voltage is applied

Many materials used in our daily life are composites, which are often made up

of at least two constituents or phases. The outstanding mechanical properties of

many composites, and especially the unique combination of low density with high

strength and stiffness have led not only to extensive research but also to a highly

developed technologies [1, 2, 3]. In comparison, relatively little attention was given

to their other physical properties, which in parallel affected their use in electrical

applications [4, 5, 6, 7]. The main advantage of composites is the ability to tailor

materials for special purposes. Their applications are evolving day by day through

the developments which lead to better precision in their manufacturing.

Designing of composite materials for electrical applications with classical trial

and error approach requires a lot of time and money. However, by using computers,

modeling desired properties of insulation systems can be estimated and corrected. The

electrical properties of the system, i.e., its conductivity and dielectric permittivity,

are influenced by the properties of the constituents, interaction between them

and geometrical configuration. One should not forget that insulating materials or

dielectrics, as Faraday called them [8], show various properties at different voltages,

temperatures, frequencies, moisture content and mechanical stresses. These should be

considered in the design as well as in the diagnostics.

From the early days of the electromagnetic field theory, predicting and calculating

the dielectric properties of mixtures has been a challenging problem of both theoretical

and practical importance [7, 5, 4, 9, 6, 10, 11, 12, 13]. In composites the polarization

of charges due to the differences between the electrical properties of the facing

constituents plays an important role. Maxwell [14] was the first to notice this

phenomenon when he considered a binary layered structure and expressed the effective

dielectric properties of the composite.

Permeability is the ratio of magnetising force (B) to the resultant magnetic field (H) in a substance and is given 'myu'

sa a symbol

Permeability (myu) = B/H.

In a similar scenario, Permittivity is the ratio of Polarising Electric force (P) to Electric field (E) and is given 'epsilon' as symbol

Permittivity (epsilon) = P/E.

Polarization of molecules is observed in a 'dielectric' (non-conducting) subsatance.

Hot - Relating to spicy or extremely heated to the point of it becoming unbearable to touch. Fine - Broken down into peices small enough to almost be considered particles. Sexy - To be considered so attractive that you would imagine having "sex" with that person. It seems by theyr definishuns that none of these words have any relashun with eachuther :)

as fer as yu question gives d answer,permeability is unit of

magnetic field and permitivity is unit of electrostatics field
