3) Consider two N-turn circular coils of radius R, each perpendicular to the axis of symmetry, with their centers located at z=+1/2 as shown in the figure. There is a steady current / flowing in the same direction around each coil, as shown in the Figure. a) Find the magnetic field B(z) on the axis at a distance z. b) Show that ƏB/&z=0 at z=0. c) Find the condition for which ô2B/az2=0 at z=0. z R î X 1 R
