摘要

In this communication, an a posteriori equilibrated error estimator for the 3D Finite Element approximation of the eddy current problem is developed. Upper and lower bounds for the error are provided. Finally some numerical tests are performed in order to validate the theoretical results and check the efficiency of the estimator.
