A coaxial cable has current on the inner conductor 8A in +x direction and returns in –x direction at the outer conductor. The inner conductor radius is 2 m and outer conductor radii are 4 and 6. Apply ampere’s law and calculate the magnitude of magnetic field inside the inner conductor. Answer Options are: r/pi ; 8/pi*r ; (8*r)/2*pi

Figure CQ19.7 shows a coaxial cable carrying current I in its
inner conductor and a return current of the same magnitude in the
opposite direction in the outer conductor. The magnetic field

(b) r 5 4r0.
A little explanation would be greatly appreciated!

magnetic field, a conducting rod (length d = 1.5 m , mass m = 110 g
) hangs from a friction-free pivot and is oriented so that its axis
of rotation is aligned with the direction of the magnetic field to
be measured. Thin flexible wires (which exert negligible force on
the rod) carry a current I = 10 A , which causes the rod to deflect
