It is a physical constant, conventionally written as μ0 (pronounced "mu nought" or "mu zero"). It quantifies the strength of the magnetic field induced by an electric current. Expressed in terms of SI base units, it has the unit kg⋅m⋅s −2 ⋅A −2. It can be also expressed in terms of SI derived units, N ⋅A −2. See more

1948International decisions were made by standards organizations to adopt the rmks system, and its related set of electrical quantities and units, as the single main international system for describing electromagnetic phenomena in the International System of Units.2019The ampere is defined exactly in terms of the elementary charge and the second, and the value of μ0 is determined experimentally.2019The permeability of vacuum no longer has a defined value, but is a measured quantity, with an uncertainty related to that of the (measured) dimensionless fine structure constant.1950sThe modern notation of permeability as μ and permittivity as ε has been in use since the 1950s.1872The terminology of permeability and susceptibility was introduced by William Thomson, 1st Baron Kelvin in 1872.1948From 1948 to 2019, μ0 had a defined value (per the former definition of the SI ampere), equal to: μ0 = 4π×10−7 H/m = 1.25663706143...×10−6 N/A22019The current in this definition needed to be measured with a known weight and known separation of the wires, defined in terms of the international standards of mass, length and time in order to produce a standard for the ampere (and this is what the Kibble balance was designed for).1987In the 1987 IUPAP Red book, for example, this constant was called the permeability of vacuum.The magnetic constant μ0 appears in Maxwell's equations, which describe the properties of electric and magnetic fields and electromagnetic radiation, and relate them to their sources. In particular, it appears in relationship to quantities such as See more
