Plants are known to be sensitive to electromagnetic fields, of which magnets are a source. The Earth is a huge magnet, with its core generating a magnetic field that influences several natural processes. Studies have shown that treating seeds with magnetic fields can improve germination by accelerating the formation of proteins in the cells. This results in faster and more robust growth. Applying magnetic fields has increased average germination rates, root and shoot growth, photosynthetic pigment content, and cell division, improving overall plant productivity. Magnetic fields can reprogram primary and secondary metabolites, enzyme activities, and plant nutrient and water uptake. This reprogramming stimulates growth and yield under favorable conditions and mitigates the effects of stress under adverse conditions, such as drought or soil contamination. The Earth's magnetic field is a constant environmental factor that affects plant growth. Strong and weak magnetic fields, compared to the Earth's magnetic field, play specific roles in plant growth and development. The objective of the manuscript is to relate the magnetic field to plants and homeopathy. A literature review study aims to gather all references found on a given topic, and the data collected came from scientific review productions found on the Scielo, Lilacs, Bvsms, and Google Scholar platforms. After identifying the articles, the following steps are taken reading all abstracts of the articles found; reading the selected articles in full after reading the abstracts; interpretive reading, and writing the text. The inclusion criteria were only original articles of qualitative and integrative reviews, available in full text, in Portuguese, English, and Spanish, which addressed the proposed theme and period. The choice was due to the scientific accuracy of the review articles.
