High permeability materials
WebMagnets (soft or hard) are increasingly being used in aerospace, telecommunication, healthcare, agriculture and automotive industries. Soft magnets have high magnetic saturation (Ms ), high magnetic permeability with low coercivity resulting in easy magnetization and demagnetization. Hard magnets have high magnetic saturation with … WebTable 1 : Permeability of FINEMET ® and ferrite Relative permeability μ r; f=10kHz f=100kHz; Nanocrystalline soft magnetic material FINEMET ® FT-3K50T: 50,000: 31,000: Mn-Zn ferrite μ 5000 material: 5,000: 5,000

Zou et al. 24 reported that the polyaniline (PAni) coated fabric with carbon nanotubes (CNTs) coating shows good SE around 23 dB with a high absorption ratio. After being washed in standard laundry detergent (OMO brand), the average SE of the coated fabric … 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.
