Fig illustrates a basic  magnetization  curve of iron  (commerical  purity grade). Using  tis plot, draw th permeability  `mu` as a function  of the magnetic  filed strength  `H`. At what  value of `H` is the  permeability  the greatest ? What is `mu_(max)` equal to ?  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/IROD_V01_C03_E01_283_Q01.png" width="80%"
