A finite-element model implemented in the open-source FreeFem++ program is presented, with the aim of introducing students to the calculation of AC losses in superconductors. With this simple approach, students can learn about the critical state model used to describe the macroscopic electromagnetic behavior of superconductors and the importance of several factors influencing the AC losses of superconductors.
