“…The effect of electromagnetic induction, at least in the case of alternating fields, is even more clearly expressed in organisms in which the presence of magnetic materials has been established in their cells. These include bacteria (Bazylinski et al, 1994;DuninBorkowski et al, 1998;Frankel, 1984), bees (Gould et al, 1980;Walker and Bitterman, 1985), fish (Becker, 1974;Quinn et al, 1981). mammals (Dunn et al, 1995), or differential cells-magnetocytes, according to Dobson and St. Pierre (1998).…”

Changes in the behavior of Morimus funereus individuals were investigated as early manifestations of the contact of a living system with a changed environment primarily established via the nervous system. These experiments were aimed at revealing possible behavioral differences of a laboratory population of cerambycid beetle M. funereus in an ''open field'' before and after exposure to an extremely low frequency magnetic field (ELF-MF, 50 Hz, 2 mT). The experimental groups were divided into several activity categories and exposed to ELF-MF. The results showed that the activity increased in the groups with medium and low motor activity, but decreased in highly active individuals. High individual variability was found in the experimental groups, as well as differences in motor activities between the sexes, both before and after exposure to ELF-MF. According to preliminary results, we assume the changes of activity in both sexes after exposure to ELF-MF. The results showed a tendency toward locomotor activity decrease, the affect being more pronounced in females. As opposed to this type of activity, stereotypic activity of males was increased after the exposure, whereas females maintained the expected tendency of decrease. However, we did not obtain statistically significant differences because of a high individual variability and a low total number of individuals in the experiment (N = 28).

“…The degree of magnetic dipole orientation of a micro-object such as a magnetotactic bacterium is proportional to the ratio of the magnetic forces and thermal energy B∕kT, where is the magnetic moment of the cell, B the ambient magnetic field, k the Boltzmann constant, and T the effective temperature. The magnetic dipole orientation is typically given by the average cosine of the orientation angle which follows the Langevin function [63]:…”

“…The AMB-1 magnetic bacteria synthesize fine crystalline particles of magnetite (Fe 3 O 4 ) which is surrounded by a thin lipid bilayer termed bacterial magnetic particles (BMPs). AMB-1 bacteria align along the weak geo-magnetic flux line due to the BMPs [9].…”
