Abstract
One or more magnetic fields having non-uniform gradients is periodically applied to a magnetic liquid stream, which is preferably isotropic and virtually free of remanence, to create perturbations in the stream so as to form droplets therefrom with substantially uniform spacing and of substantially uniform size. If more than one of the magnetic fields is applied, the maximum strength of each field is spaced an integral multiple wave length from the maximum strength of the adjacent magnetic field with each magnetic field having substantially the same maximum strength. The wave length of the perturbation is preferably between 4d and 8d where d is the diameter of the stream.
