This article is a summary of a full paper that will be presented at the X International PAMIR International Conference - Fundamental and Applied MHD, to be held from 20 – 24 June, in Cagliari, Italy. In the framework of the ASTRID R&D programme, it has been proposed to use an electromagnetic (EM) induction pump in the secondary cooling system. This paper describes the current status of the experimental and numerical analysis in progress to investigate liquid sodium flow instabilities in the PEMDYN loop with the objective of better managing the EM pump and preventing magnetohydrodynamic (MHD) instability. This paper discusses the analysis of 3D measurements of the magnetic fields along a path inside the annular linear induction pump (ALIP) channel measured with a Hall sensor. It also describes the numerical finite-element models that have been built to gain a more in-depth understanding of the interdependent MHD phenomena specific to EM pump operation. These measurements were obtained before the operative condition so as to retrieve as much information as possible on the EM field inside the channel pump without the fluid dynamics
