  A large aperture, thin septum, high field opposite-field septum magnet has been developed for the injection of 50GeV main ring of J-PARC. Due to the eddy current generated in septum conductor, magnet yoke and magnet end plate, the field distribution was degraded. In the paper, eddy current effects on both transverse field and longitudinal field distribution are calculated. Correction methods and experiment results are introduced.
