A long, hollow, cylindrical conductor (inner radius 2.3 mm, outer radius 6.9 mm) carries a current of 54 A distributed uniformly across its cross section. A long thin wire that is coaxial with the cylinder carries a current of 40 A in the opposite direction. What is the magnitude of the magnetic field (a) 1.2 mm, (b) 2.5 mm, and (c) 7.0 mm from the central axis of the wire and cylinder? (a) Number i -9 (b) Number i 2310 (c) Number .39 Units mT Units mT Units mT
