The influence of magnetic fields (MFs) on the behavior of biological systems is an active area of biophysics research. Low-intensity MFs are of particular interest, as they are ubiquitous in the modern world and have been shown to affect living organisms, including avian navigation. Mechanisms from quantum biology, such as the radical pair mechanism, have been proposed to explain these phenomena. However, the effects of low-intensity MFs on microorganisms, especially fungi, remain to be elucidated. In the first part of this thesis, a low-MF exposure device was engineered for magnetobiology experiments. First, the device was designed in SolidWorks. Next, the 20-100 mT MFs within the device were simulated in COMSOL Multiphysics to optimize MF homogeneity and magnetic flux density, incorporating Neodymium permanent magnets.
