This paper focuses on numerical and experimental investigation of magnetohydrodynamic (MHD) instability which can occur in an electromagnetic induction pump (EMIP) in regimes when slip Magnetic Reynolds number (Rms) is sufficiently high. It has been reported that MHD instability produces strong non-homogeneity of flow, low frequency pressure pulsations, vibrations and drop of developed pressure therefore it should be regarded as highly unwanted phenomenon. Detailed studies of this problem must be carried out to develop better understanding about working regimes and master control of EMIP.
