The first video shows magnetotactic bacteria influenced by a magnetic field strength of 7.53x10^(-6) Tesla. The field direction controls the alignment of the bacteria, but not the speed that they travel at. The higher the field direction, the stronger the alignment of the bacteria with the field direction.

The second video acts as a comparison against the magnetotactic control, using chemotaxis. The bacteria detect a change in the chemical concentration, and move towards the higher concentration, i.e. up the chemical gradient.
