Formula of relative permeability
Did you know?
WebRelative Permeability. Relative permeability is defined as the ratio of a medium's permeability to the permeability of free space. As a result, a medium's relative permeability is a dimensionless quantity that may be represented as μr = µ/μ 0. The relative permeability of open space, according to this concept, is 1. Web[Equation 2] The permeability of a medium () is most often quoted in terms of its relative permeability , which is a measure of the permeability of a medium relative to that of a vacuum: [Equation 3] The relative permeability of a medium can actually be less than 1. This is known as Diamagnetism.
