A long, straight cylindrical conductor having radius R = 7.50 cm carries a constant current I = 160 A. The current density is uniform above the cross-sectional area of the conductor.
(i) Determine the magnitude of the magnetic field (in T) at a radial distance r1 = 5.50 cm from the center of conductor?
(ii) Determine the magnitude of the magnetic field (in T) at a radial distance r2 = 8.30 cm from the center of conductor?
