Answer
$μ = 7.54 \times 10^{-3} H/m$
Work Step by Step
Given:
magnetization M = $1.2 \times 10^{6} A/m$
H field = 200 A/m
$χ_{m} = 6000$
Required:
permeability
Solution:
Using the combined form of Equations 20.4 and 20.7:
$μ = μ_{r} μ_{0} = (χ_{m} + 1)μ_{0} = (6000 +1)(1.257 \times 10^{-6} H/m) = 7.54 \times 10^{-3} H/m$
