Magnetic fields, different to electric fields, can intrude into deeper layers of tissue, where they could modulate biochemical processes. In this context, we explored the cellular effects of specifically designed high-performance micro-magnet arrays which, in contrast to conventional magnets, generate high-gradient magnetic fields not encountered in the environment. Exposure of monocytic cells to high-gradient magnetic fields of various strength generated by micro-magnet arrays induced cell swelling followed by accumulation of reactive oxygen species (ROS), and inhibition of cell proliferation. High levels of ROS may damage cellular structures and induce apoptosis. Consistently, prolonged exposure of cells to high-gradient magnetic fields induced time-dependent translocation of phosphatidylserine to the outer leaflet of the membrane.
