How to detect magnetic permiablity?
Answers
Magnetic permeability, relative increase or decrease in the resultant magnetic field inside a material compared with the magnetizing field in which the given material is located; or the property of a material that is equal to the magnetic flux density B established within the material by a magnetizing field divided by the magnetic field strength H of the magnetizing field. Magnetic permeability μ (Greek mu) is thus defined as μ = B/H. Magnetic flux density B is a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area. Magnetic field strength H is a measure of the magnetizing field produced by electric current flow in a coil of wire.

Answer:
Permeability is the inductance per unit length. 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).
