The figure below is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a ruber layer, conductor is \( I_{1}=1.10 \mathrm{~A} \) out of the page and the current in the outer conductor is \( I_{2}=2.84 \mathrm{~A} \) into the page, Assuming the distance \( d=1.00 \) mm, answer the fo (a) Determine the magnitude and direction of the magnetic field at point \( a \). magnitude If you construct an imaginary circle of radius \( d \) passing through point \( a \), how much current passes through this circle? \( \mu T \) direction (b) Determine the magnitude and direction of the magnetic field at point \( b \). magnitude \( \quad \mu \mathrm{T} \) direction
