What is the SI unit of permeability

Options

A. Henry per metre
B. Tesla metre per ampere
C. Weber per ampere metre
D. All the above units are correct

Answer

D

Explanation

`B=mu_0nI=mu_0N/IIimplies mu_0=(BI)/(NI)`
Tesla meter per ampere
`mu_0=(Wb//m^2 xxm)/("ampere")=Wbm^(-1)A^(-1)`
Henry `=(Wb)/Aimpliesmu_0=(Wb//A)/(m) =` Henry per meter.
