Permittivity (ε) applies to electric fields, and permeability (μ) refers to magnetic fields.
In electromagnetism, permeability is the measure of the ability of a material to support the formation of a magnetic field within itself AND permittivity is the measure of how much resistance is encountered when forming an electric field in a medium.
Also their relation is given by
v= 1

1/2
(ε*μ)
v=velocity of light.

∙ 13y agoIn geology, permeability is the capacity of a rock or sediment to move water or other fluids through it's pore space. Things with high permeability would be things like beach sand or a loosely packed sandstone, and things will low permeability would be things like granites and other igneous porphyries.

Can a rock have high porosity but low permeability?
Yes for example Clay has high porosity and low permeability
What is an accurate description of clay soil?
high porosity, low permeability
What rock is low in porosity and low in permeability?
Most intrusive igneous rock is low in porosity and permeability.
Why Soft Iron is suitable for preparing pole pieces in earphones as well as loudspeakers instead of steel?
Soft iron is suitable for preparing pole pieces in headphones as well as loudspeakers instead of steel because soft iron materials have high permeability and low coercive force. They are easily magnetized and demagnetized. Examples of soft magnetic material are silica-steel (Fe-97 and Si-3), Sandust (Al-5, Si-10, Fe-85). Soft iron materials have following characteristics:- Thin hysteresis loop. High permeability. Low coercivity. High susceptibility. Low hysteresis loss. Low eddy current loss. Whereas materials made up of steel have totally different properties i.e. High permeability and High hysteresis loss. Large hysteresis loop. High coercivity residual magnetism.
Which is an accurate description of silty soil?
moderate porosity, low permeability
Does silt have high permeability?
Silt has neither high or low permeability. It has moderate permeability. :) !

What makes soft iron a suitable core for transformers?
Low hysterisis loss and high permeability
What material should have high electro magnetic property?
A material with high initial permeability and low retentivity have electromagnetic property.
If a material has a high conductivity does it have a high permeability and if so what would be an approximate permeability for the high conductive material?

What type of soil has low permeability and poor crop-growing potential and high nutrient-holding capacity?
Clay soils.
What does high porosity and low permeability mean?
Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.
What type of hawaiian rocks have low permeability?
Basalt
Why sheet steel with high silicon content is used in transformer core whereas lower silicon content sheet for rotating machine?
high permeability ,low hysterisis,increased resistivity
