Experimental set up and seedling growth. A) Three samples were exposed simultaneously to the magnetic field, in three different positions within the magnet bore: 0 g*, 1 g* and 2 g* tubes. An additional sample was maintained under the same conditions, except for the magnetic field, outside the magnet (1 g control). B) Effective gravity acting on water within the 0 g* tube. The colour scale indicates the magnitude of the effective gravity as percent of the ground gravity g. Arrows show the magnitude and direction of the effective gravity vector. C) Image taken of the sample tube located at the 0 g* position, after the 4-day experiment. After growing in darkness, seedlings show a clear orientation according to the gravity vector.
