Prototype development to expose bacterial cultures to magnetic fields

Magnetic and electromagnetic fields are widely used in our environment. However, their effects on living tissues are quite unknown, and the existing results obtained from former researches are not conclusive. Objective: To develop a prototype that allows an evaluation of the bacterial culture exposed to magnetic fields generated by two ferrite magnets attracted to each other. Methods: The prototype was built with acrylic plates of different sizes and formats. Two circular ferrite magnets were fixed to the plates, attracted to each other, in order to generate a magnetic field of 100 ± 5 mT. Test tubes were adapted in the prototype to allow bacterial growth in broth under stimulation. Results: Inthe present pilot study, the prototype was effective in exposing bacterial cultures to a magnetic field. Conclusion: The developed prototype served to the purpose of the study and made possible to expose bacterial cultures to a static magnetic field.
