A systematic study of flux pinning and the thermodynamic critical field Hc has been undertaken to determine whether Hc is a central factor determining the critical current Jc. Materials that have a fairly wide temperature interval of thermodynamic reversibility are selected so that the thermodynamic critical field can be confidently extrapolated into the irreversible regime. Jc is found to scale with Hc. For a given sample, the Jc/Hc vs H/Hc curves are close to a universal function as temperature changes. In addition, the peak in the pinning force curve also scales with H2c for a wide variety of samples having quite different transition temperatures.
