Q1. A long hollow cylindrical conductor (inner radius = 2.0 mm, outer radius = 4.0 mm) carries a current of 13 A distributed uniformly across its cross section. A long wire which is coaxial with the cylinder carries an equal current in the similar direction. What is the magnitude of the magnetic field 3.4 mm from the axis?
