The dynamics of the dust structures created in striations in the glow discharge in a magnetic field has a complex character which is shown in the inversion of the direction of the movement. The hypothesis of existence of eddy current in the striation which in the magnetic field causes the rotation of dust structures by means of the Ampère force has been offered and developed in the recent works of Nedospasov et al. and Dyachkov et al. In the present work, the experiment in which eddy current in various phases of striations is registered by means of probing dust particles is carried out. It is shown that for various discharge conditions and various magnetic fields the dragging by the rotating gas and the ion drag are the dominating forces defining the dynamics of dust structures in striations.
