In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside … Zobraziť viac In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • the magnetizing field H which is generated around electric currents and displacement currents, … Zobraziť viac Diamagnetism is the property of an object which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus causing a repulsive effect. Specifically, an external magnetic field alters the orbital velocity of electrons around their … Zobraziť viac For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic … Zobraziť viac • Antiferromagnetism • Diamagnetism • Electromagnet Zobraziť viac Relative permeability, denoted by the symbol $${\displaystyle \mu _{\mathrm {r} }}$$, is the ratio of the permeability of a specific medium to the permeability of free space μ0: where Zobraziť viac Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field.

The search for new formulations for transdermal drug delivery (TDD) is an important field in medicine and cosmetology. Molecules with specific physicochemical properties which can increase the permeability of active ingredients across the stratum corneum (SC) are called chemical penetration enhancers (CPEs), and it was shown that …
WebThe various types of in situ tests commonly used to determine the permeability of aquifers in the field are: 1. Pumping-out test. 2. Pumping-in Test. Compared with laboratory methods, field methods give a more reliable value of permeability, since the soil is tested in situ without disturbing its structure and void ratio.
