Question

an iron core has 250 time more flux density than air for the same field intensity.what is the value of relative permeability​

Answer 1

answer:

B = µ * H , where µ is the permeability, M = χ * H , where χ is the magnetic susceptibility (check Curie's law calculator), B = µ₀ * (H + M) , where µ₀ = 4 * π * 10^(-7) H/m is the magnetic permeability of free space. The unit H is called "henry" and it is an unit of inductance
