The plane z = 0 separates air (z 0, = ) from a conductor (z 0, = 100

The plane z = 0 separates air (z ≥ 0, μ = μ_º) from a conductor (z ≤ 0, μ = 100μ_º). The magnetic field in air is given by

H = 10a_x + 15a_y - 3a_zA/m

Find the magnetic field in conductor and the angle it makes with the normal to the interface
