Question: 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

The following data are for a transformer steel:

B B ( m) H (A/m) (teslas) (teslas) 200 1.04 10 0.03

(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 permeabilitycorrespond?

B B ( m) H (A/m) (teslas) (teslas) 200 1.04 10 0.03 400 1.28 600 20 0.07 1.36 1.39 800 50 0.23 0.70 1000 1.41 100 150 0.92
