Question

How do you know the permeability?


Open in App
Solution

Explanation:

  1. Permeability is a measure of a material's ability to allow the creation of magnetic lines of force or magnetic fields within it.
  2. It refers to the material's magnetization ability in relation to the applied magnetic field.
  3. Magnetic permeability can be defined as "the extent to which magnetic field lines can penetrate a substance" or “the power of a substance to conduct magnetic field lines.”
  4. The Greek alphabet μ represents it.

The table below shows the mathematical representation of permeability, the SI unit, and the dimensional formula:

  1. Dimensions: MLT-2A-2
  2. S.I. unit: HmorTmA-1, Where H is Henries.
  3. Mathematical representation: Permeability=Magnitudeofmagneticinduction(β)Intensityofmagneticfield(H)
  4. Mathematical representation:μ=βH

Hence, this is the way to know the permeability.
