Magnetic moments for different magnetotactic microorganisms are obtained by electron microscopic analyses and studies of cell motion by optical microscopy. The results are analysed in terms of a model due to C. Bean. The considerations presented suggest that magnetotaxis is an efficient mechanism for orientation only if the time for reorientation is smaller than the mean time of environmental perturbations.
