Quantum Mechanics and Electromagnetics of Weak Magnetic Field Sensing, Storage and Retrieval in Biosystems and Engineered Systems

We study phenomena and effects which can be utilized to sense weak magnetic fields by engineered systems. Possible mechanisms and phenomena utilized by living systems are outlined and discussed. Assuming the macroscopic device physics, it is found that only fluidic engineered devices can typify a magnetoreception premise believed be utilized by some living systems. It is found that the mechanical properties of silicon-technology solid devices may not coherently utilize possible behavioral transitions and functionality exhibited by natural systems. Hybrid microdevices is an alternative solution which we examine in details. Fundamental, applied, experimental and technological findings are reported.
