The magnetic model of the superparamagnetic magnetite magnetoreception

Abstract:

The model of biomagnetite magnetoreceptions include the model of single-domain magnetite magnetoreception and the model of superparamagnetic magnetite magnetoreception. In honeybees, there are many typical superparamagnetic magnetites, so in this paper, the magnetic model and working mechanism of the superparamagnetic magnetite magnetoreception are discussed qualitatively from the point of view of theory of magnetism taking the example of honeybees. In the outer magnetic field, each superparamagnetic magnetite can be act on with the size extend or contract along different directions. Superparamagnetic magnetites transmit the force and change of size to the outer biomembrane and eukaryotic cytoskeleton which embedding in the nervous system, so a nerve signal can be produced. The signals can be magnified because many superparamagnetic magnetites exist.
