WebGenerally, chemical flooding is conducted in a high permeability reservoir. This section describes an experimental study of the application of surfactant flooding in a low … 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 Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic … See more The following table should be used with caution as the permeability of ferromagnetic materials varies greatly with field strength. For example, 4% Si steel has an initial relative permeability (at or near 0 T) of 2,000 and a maximum of 35,000 and, indeed, the relative … 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 … 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 causing a repulsive effect. Specifically, … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic field in the microwave frequency domain is treated as a non-diagonal tensor expressed by: See more WebHigh Permeability "49" is a 48% nickel-iron alloy that possesses the highest saturation flux density of any nickel-iron alloy.
