A recent study utilized a sensitive atomic magnetometer to measure the electromagnetic field (EMF) of a plant. We aimed to use a simplified method for recording direct and indirect images of EMFs from the leaves of the plant, Vigna radiata. Protocol 1. Consisted of Iron particle solutions of 200 or 2000 nanometers (nm) and Prussian Blue stain (PBS) which were applied to leaves in a 2 glass slide “sandwich”. When the liquid had dried, the leaves were microphotographed. Protocol 2. Leaves prepared as in Protocol 1 were then covered by a second pair of slides within which was a solution of iron particles and PBS. Protocol 3. Six pairs of leaves treated with solutions of iron particles and PBS or deionized water for 24 hours were analyzed by magnetic resonance imaging (MRI). Leaves with direct and indirect contact with the iron particle/PBS solutions showed aggregation of iron particles outlining the leaf edges and leaf hairs (trichomes, Protocol 1) or EMF images of leaf edges, trichomes as well as interior veins were seen in slides containing iron particles and PBS not directly in contact with the leaves (Protocol 2). Protocol 3: MRI studies (n=12) allowed a quantitative comparison of leaves treated with iron particles compared to those exposed to deionized water. In the former group, there was a significant loss of T2 values indicative of the replacement of water by iron particles adherent to the treated leaves, p≤0.0001 compared to the group in deionized water. Nanometer sized paramagnetic iron particles can be used to demonstrate the EMF of the leaves of the plant Vigna radiata. Journal of Nature and Science, 1(4):e61, 2015.
