Magnetic separation processes in living organisms and embryo development

Numerous magnetic devices for magneto-therapy including steady magnets with various forms and sizes are widely produced. In such devices the gradient magnetic fields are combined with needed mechanical vibrations. Magnetic concentration effects occur always in living systems because gradient magnetic fields inside organism are strong enough to cause drifts of cellular complexes and organelles by micron and submicron sizes. In the present article we report on the appearance of super-paramagnetic contaminations inside developing eggs of Artemia shrimps. In developing shrimps eggs ferritin aggregates were observed under weak gradient magnetic fields and dia-para-ferromagnetic transitions were detected. A significant interruption of eggs’ developing was revealed in such fields.
