The internal magnetic field distribution in a type‐II superconducting cylindrical shell is determined. The superheating – and the supercooling – fields are developed. The effect is shown of a transport current on the creation and annihilating of the potential barrier for high χ‐cylindrical shell. The ac losses are studied in the frame of the general critical state theory. For a high‐ T c superconducting sample, smaller superheating – and supercooling – fields than that for conventional superconductors are obtained.
