Alignment of AMB-1 during global external magnetic field application. (a) Schematic of coordinates indicating the angle (in b, c) of the AMB-1 cell body with respect to the positive x axis, the direction of the magnetic field direction. (b) Histogram of the orientation of AMB-1 motility direction with no external applied magnetic field (see (a) for angle). (c) Histogram of the orientation of AMB-1 motility with 1.0 mT external magnetic field applied along the x axis (see (a) for angle). (d) Percentage of MTB aligned at 0° with increasing externally applied magnetic field strength. A maximum response (saturation) appears to occur at ∼1.1 mT where 90% of the bacteria are completely aligned with the direction of the external magnetic field.
