The region of space x < 0 (region 1) is filled with magnetic material of permeability 2001 0, while the region x > 0 (region 2) is air of permeability 0. In the region x < 0 (region 1), the magnetization is uniform and given by 1 = 30 2 + 50 (A/m). There is no free current on the interface at x = 0. a. Find the magnetic field strength 1 in region 1 (x < 0). b. Give the normal and tangential components of 1 c. Find the magnetic field strength 2 in region 2 (x > 0)
