Small oscillations of a hot plasma confined by the pressure of a magnetic field are treated with aid of the kinetic equation in the "drift" approximation without the collision integral. Two types of waves can exist for the wave vector lying in a plane perpendicular to the direction of the unperturbed magnetic field. One of these is a slow (drift) wave with a propagation velocity of the order of the mean electron lion) drift velocity in the unperturbed state and the other is a magnetoacoustic wave. The first type of wave is characteristic only of an inhomogeneous plasma. For a certain interdependence between the zero magnetic field gradients, plasma density, and plasma temperature, the drift current in the unperturbed plasma may lead to amplification of such oscillations. The criteria for instability of this type were obtained. (auth)
