An infinite filament on the z axis carries 20 mA in the a, direction. Three uniform cylindrical current sheets are also present: 400 mA/m at p = 1 cm, -250 mA/m at p = 2 cm, and -300 mA/m at p = 3 cm. Calculate Ho at p= 0.5, 1.5, 2.5, and 3.5 cm: We find H, at each of the required radii by applying Ampere's circuital law to circular paths of those radii; the paths are centered on the z axis. So, at p₁ = 0.5 cm:

. An infinite filament on the z axis carries 20 mA in the a direction. Three uniform cylindrical
current sheets are also present: 400 mA/m at p = 1 cm, -250 mA/m at p= 2 cm, and -300
mA/m at p = 3 cm. Calculate Ho at p = 0.5, 1.5, 2.5, and 3.5 cm: We find H, at each of the
required radii by applying Ampere's circuital law to circular paths of those radii; the paths
are centered on the z axis. So, at p₁ = 0.5 cm:
