abstract：:An attempt was made to test the hypothesis (McLeod et al. 1987; Smith et al. 1987) that a certain combination of direct current and alternating current magnetic field exposures at room temperature results in an increase in motility of a marine diatom (Amphora coffeaeformis) to a maximum value. Diatom motility increase...
