Question

derive different units of permeability

Answer 1

In SI units, permeability is measured in henries per metre (H⋅m−1 = J/(A2⋅m) = N⋅A−2).

The auxiliary magnetic field H has dimensions current per unit length and is measured in units of amperes per metre (A⋅m−1).

Answer 2

Answer:

Permeability is typically represented by the (italicized) Greek letter μ. The term was coined in September 1885 by Oliver Heaviside. The reciprocal of permeability is magnetic reluctivity. In SI units, permeability is measured in henries per meter (H/m), or equivalently in newtons per ampere squared (N⋅A−2).
