Abstract: Since, the beginning of time, every living organism under the expose of sun rays lived under the inevitable environmental influence of Magnetic Field (MF). The role of the magnetic field and their influence on nutrients modification, microorganism and the biological system is becoming more and more important as new evidence reveals the ability of plants and microorganism to perceive and respond quickly to varying MF by altering their gene expression and phenotype. The literature reviewed has shown a high sensitivity of plants and microorganisms to permanent magnetic fields, in particular, in the intensity range from MF level to very low ones. The external application of electromagnetic fields in plant science and microbiology has shown to influence both the activation of ions and the polarization of dipoles in living cells and the rapid growth of different crops in comparison to control. Literature relived that magnetic field achieves such results by changing the molecular distribution of electronic charge inside each lipid molecule, producing perturbations of collective excitations in the mechanical and electrical properties of the lipid chain which can be treated as a mechanism for intermembrane communication, analogous to a damped harmonic oscillation. Magnetic field strength ranging from (0.0, 20.0, 40.0 and 60.0 mT) encourages nutrient uptake such Ni, Sr, K, Cu, Mg, Fe, Mn, Ca, Zn, Co and V and essential amino acids such as histidine and decreases ion toxicity. However, the results of magnetic field stimulation can be seen after 7th day to 14th day of the treatment.
