The following data are for a transformer steel:

(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?
