Abstract
The paper describes an efficient method to extract the B-H nonlinear charac teristic from the experimental flux-current Phi-I data obtained using a non -uniform magnetic field device. Both functions are monotonically piecewise linear approximated with the same number of breakpoints. The method was suc cessfully applied to characterize the ribbon core material of a fluxset mag netic field sector. In this case the hysteresis loop and the lumped magneti c circuit were extracted. Comparison with experimental results validates th e proposed method.
