The electromagnetic properties of an MgB2 superconductor depend on a matrix metal. Therefore, the design principles of an MgB2 magnet are greatly affected by the matrix metal of the conductor. A ferromagnetic matrix requires a complex nonlinear modeling whereas in case of non-magnetic matrix the models developed for LTS magnets can be adopted. In this paper a design analyses of linear and non-linear MgB2 coils are compared. Also, feasibility of linear model in non-linear case is studied. As an example a design scheme of a mu-SMES solenoid with MgB2-W/Fe and MgB2-SiC/Nb/AgMg wires is outlined.
