Expenrimental results of Jc(B) in high magnetic fields for diffusion and CVD Nb3Sn tapes and MF Nb3Sn wires have been analysed by using regression analysis, the empirical rules for Jc(B) and FP(B) in high magnetic fields were obtained. The rules are different from Kramer scaling law. There is a need for a new model of flux pinning mechanism to explain the empirical rules.
