The dimensional formula of permeability of free space μ0 is
WebThe dimensional formula of permeability can be represented as, [M1 L1 T-2 I-2] Here, M = Mass I = Current L = Length T = Time Derivation: We have, Magnetic Permeability (μ) = Magnetic flux density × [Magnetic field strength] -1 . . . . (1) As because, Force = magnetic flux density × current × length WebDec 24, 2014 · Permittivity of free space in cgs units is 1. In electrostatic CGS, epsilon_0 is 1/4pi and it is unitless. This is probably what you want. In other versions of the CGS system it can be different ... μ0 = 4π × 10−7 H/m = 1.256 637 061 43... × 10−6 N /A2 (1 henry per metre = 1 newton per square ampere = 1 tesla metre per ampere) The deviation of the recommended measured value from the former defined value is statistically significant, at about 3.6 σ, listed as μ0 / ( 4π × 10−7 N⋅A−2 ) − 1 = (5.5 ± 1.5) × 10−10. [4] See more The vacuum magnetic permeability (variously vacuum permeability, permeability of free space, permeability of vacuum), also known as the magnetic constant, is the magnetic permeability in a classical vacuum. … See more Standards organizations have recently moved to magnetic constant as the preferred name for μ0, although the older name continues to be listed as a synonym. Historically, the constant μ0 has had different names. In the 1987 IUPAP Red book, for example, … See more The magnetic constant μ0 appears in Maxwell's equations, which describe the properties of electric and magnetic fields and See more 1. ^ This choice defines the SI unit of current, the ampere: "Unit of electric current (ampere)".
