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.
In 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.
Yes for example Clay has high porosity and low permeability
high porosity, low permeability
Most intrusive igneous rock is low in porosity and permeability.
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.
moderate porosity, low permeability
Silt has neither high or low permeability. It has moderate permeability. :) !

Low hysterisis loss and high permeability
A material with high initial permeability and low retentivity have electromagnetic property.
ni ata answer
Clay soils.
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.
Basalt
high permeability ,low hysterisis,increased resistivity
