Iron relative permeability

WebRelative permeability of iron is 5500. Its magnetic susceptibility will be A 5499 B 5500×107 C 5500×10−7 D 5501 Solution The correct option is A 5499 Given μr = 5500 Using relation, μr = 1+x ⇒ x= μr−1 = 5500 - 1 x = 5499 Suggest Corrections 0 Similar questions Q. Relative permeability of iron is 5500, then its magnetic susceptibility will be: Q. WebBecause soft iron is easily magnetized, so it has a high permeability. The permeability of a material is a measure of how easy it is for flux lines to pass through it. Numerical values …

WebThe initial permeability idefines the relative permeability at very low excitation levels and constitutes the most important means of comparison for soft magnetic materials. According to IEC 60401-3, i is defined using closed magnetic circuits (e .g. a closed ring-shaped cylindrical coil) for f 10 kHz, B <0.25 mT, T = 25 °C. WebThe permeability of ferromagnetic materials is not constant, but depends on H. In saturable materials the relative permeability increases with H to a maximum, then as it approaches saturation inverts and decreases toward one. [2] [3] Different materials have different saturation levels.
