An irregular magnetic field generated by screening current in rare-earth barium copper oxide (REBCO) coated conductor is undesired, when REBCO magnets are applied to magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR), particle accelerators. The screening current-induced fields (SCIF) have been evaluated in not only experiments but simulations. A few numerical methods have been proposed for screening current simulation. Since these methods have different characteristics, they are compared. Furthermore, a new screening current simulation model, named “ladder equiv- alent circuit model,” is proposed.
