In this work, we provided direct evidence for the first time that exposure to a static magnetic field (SMF) of low intensity (2 mT) is immediately followed by a reversible cell membrane depolarization wave (of about 1 min) that causes the rise of intracellular calcium and the decrease of mitochondrial activity of vital granulosa cells. These effects are likely due to the increase in Na + and Ca 2+ cell membrane permeability. Bioelectromagnetics. 35:231–234, 2014. © 2014 Wiley Periodicals, Inc.
