The numerical simulation of complex, nonlinear and coupled, electromagnetic and thermal dynamics involved in the quench phenomena of Magnesium Diboride (MgB2) superconducting magnets requires a suitable modeling of the interaction among the different aspects. As a matter of fact, magnets wound using MgB2 tapes are characterized by material parameters and working temperatures leading to different behaviors with respect to either Low superconductors (LTS) and High (HTS) superconductors, and thus requiring special care in the modeling of quench diffusion phenomena. In this paper, a 3-D finite-element method (FEM) model able to cope with such phenomena is presented and model predictions are compared to experimental data.
