Vacuum permeability
text:
The vacuum magnetic permeability is the magnetic permeability in a classical vacuum. It is a physical constant, conventionally written as μ0. 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. Since the revision of the SI in 2019, μ0 is an experimentally determined constant, its value being proportional to the dimensionless fine-structure
