Electromagnetic drift instabilities are considered for tandem mirror and field reversed plasma configurations taking into account effects of magnetic drift and finite ( = plasma pressure / magnetic pressure). Stabilization of drift modes due to finite plasma length along magnetic field lines is studied. Dispersion equation includes effects of the common actions of gradients of plasma density, ion temperature and electron temperature with no assumption of adiabatic response of ions or electrons for the ranges of perpendicular wave number values from k[perpindicular] < 1/Ti up to k[perpindicular] ~ 1/Te (Ti and Te are ion and electron thermal gyroradiuses). Instability induced turbulent transport is considered for mirror and field reversed magnetic configurations. Effect of sheared E × B flow on fluctuation level and transport is discussed.
