Given a material for which χm = 3.1 and within which B = 0.4yaz T, find (a)H; (b) µ; (c) µr; (d) M; (e) J; ( f ) JB; (g) JT
2. Find H in a material where (a) µr = 4.2, there are 2.7 × 10^{29 }atoms/m^{3}, and each atom has a dipole moment of 2.6 × 10^{−30}ay A · m2; (b) M = 270az A/m and µ = 2µ H/m; (c) χm = 0.7 and B = 2az T. (d) Find M in a material where bound surface current densities of 12az A/m and −9az A/m exist at ρ = 0.3 m and 0.4 m, respectively.
