The x–y plane separates two magnetic media with magnetic

The x–y plane separates two magnetic media with magnetic permeabilities µ1 and µ2, as shown in Fig. 5-45 (P5.30). If there is no surface current at the interface and the magnetic field in medium 1 is
H1 – xH1x yH1y zH1z
Find: _
(a) H2,
(b) ?1 and ?2, and
(c) Evaluate H2, ?1, and ?2 for H1x = 2 (A/m), H1y = 0, H1z 4 (A/m), µ1 = µ0, and µ2 = 4µ0.
