Abstract:Because the HTS MRI magnet was wound with coated conductor with magnetic substrate, we examine the influence of magnetic substrate on the magnetic field at first. Then, we analyzed the shielding-current-induced field of coils using the E-J characteristic described by percolation de-pinning model.
