Low frequency fluctuations in the JFT‐2 tokamak are investigated. The fluctuations propagate in the direction of the electron diamagnetic drift velocity and have a toroidal mode numbern=1. Density fluctuations reveal that them=2 mode is dominant; on the other hand, magnetic field fluctuations show a poloidal mode numberm=3. The apparent discrepancy is explained by a sum ofm=2,m=3, and/orm=4 modes. Theoretical analysis based on the magnetohydrodynamic theory of kink and tearing modes agrees well with experimental observations.
