The following data are for a plain carbon steel alloy:

(a)Construct a graph of B versus H.
(b)What are the values of the initial permeability and initial relative permeability?
(c)What is the value of the maximum permeability?
(d)At about what H field does this maximum permeability occur?
(e)To what magnetic susceptibility does this maximum permeability correspond?
