The effects of static 3.0 T and 0.5 T magnetic fields and the echo-planar imaging experiment at 0.5 T on E. coli

Various mutant strains of Escherichia coli have been exposed to a homogeneous static magnetic field of either 0.5 T or 3.0 T and to the time varying magnetic fields found in echo-planar imaging experiments. No evidence of increased DNA damage was detected, even with bacterial strains disabled for DNA repair.
