Figure \( 29-49 \) shows a cross section across a diameter of a long cylindrical conductor of radius \( a=2.00 \mathrm{~cm} \) carrying uniform current \( 170 \mathrm{~A} \). What is the magnitude of the current's magnetic field at radial distance (a) 0, (b) \( 6.00 \mathrm{~mm} \), (c) \( 2.00 \mathrm{~cm} \) (wire's surface), and (d) \( 5.90 \mathrm{~cm} \) ?
