This in vitro study examines a spinning oscillating magnetic field (sOMF) generated by an Oncomagnetic device and reports selective toxicity in glioma cancer cells. The abstract attributes effects to ROS-dependent inhibition of mitochondrial complex I, with downstream oxidative stress, DNA damage, cell-cycle arrest, and apoptosis. It also reports no similar toxic effects in normal human astrocytes/astroglial cells under the studied conditions.
