Electromagnetism is a fascinating natural phenomenon that can be visually demonstrated using certain plants in outdoor plant boxes. These plants respond to electromagnetic fields, making them ideal for educational experiments and science projects. Here are some of the best plants to showcase electromagnetism outdoors:

1. Sunflowers (Helianthus annuus) – Known for their heliotropic movement, sunflowers subtly align with electromagnetic fields, making them a great choice for demonstrations.

2. Mimosa Pudica (Sensitive Plant) – This plant reacts to touch and electrical stimuli, showcasing rapid leaf movement when exposed to weak electromagnetic pulses.

3. Pea Plants (Pisum sativum) – Studies suggest pea roots exhibit directional growth in response to electromagnetic fields, making them useful for experiments.

4. Wheatgrass (Triticum aestivum) – Its rapid growth and sensitivity to environmental changes, including electromagnetic waves, make it a practical option.

5. Bean Sprouts (Phaseolus vulgaris) – These sprouts show altered growth patterns under electromagnetic influence, ideal for classroom demonstrations.

For optimal results, place these plants in well-drained outdoor plant boxes with controlled electromagnetic exposure. This setup not only highlights plant responses but also engages learners in hands-on science exploration.
