High permeability
WebFeb 27, 2024 · High permeability in soil means that water can move quickly and easily, so it drains away faster. Soils with high permeability have a lot of sand. Sand particles don’t absorb any water but their granular size and inability to stick together leaves plenty of little gaps (high porosity). High permeability soils have: A good magnetic core material must have high permeability. For passive magnetic levitation a relative permeability below 1 is needed (corresponding to a negative susceptibility). Permeability varies with a magnetic field. Values shown above are approximate and valid only at the magnetic fields shown. See more 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 See more Relative permeability, denoted by the symbol $${\displaystyle \mu _{\mathrm {r} }}$$, is the ratio of the permeability of a specific medium to … See more Diamagnetism is the property of an object which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic … See more 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, and also emanates from the poles of magnets. … See more Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field.

A pure phospholipid bilayer, whatever the lipid composition, is a semi-permeable membrane that is generally repellent to large molecules and to ions. Small polar molecules can sometimes pass easily (e.g. ethanol), but more often pass at low rates if at all (e.g. water).
WebHigh Permeability "49" is a 48% nickel-iron alloy that possesses the highest saturation flux density of any nickel-iron alloy. The saturation flux density of about 16000 gauss (1.6 tesla) combined with its high initial and maximum permeability and low core loss after heat treatment make this a versatile alloy with many potential applications.
