Inductance of coaxial cable.
A long coaxial cable consists of two thin-walled conducting cylinders with inner radius 2 c m and outer radius 8 c m. The inner cylinder carries a steady current 0. 1 A, and the outer cylinder provides the return path for that current. The current produces a magnetic field between the two cylinders.
