Conducting a magnetic field experiment with plants in outdoor plant boxes is an exciting way to explore geomagnetic effects on plant growth. Here’s a step-by-step guide to set up your own DIY project:

1. Materials Needed:

- Outdoor plant boxes (wooden or plastic)

- Small neodymium magnets or electromagnetic coils

- Fast-growing plant seeds (e.g., beans or sunflowers)

- Soil, water, and measuring tools

- A compass or Gauss meter (optional, to measure field strength)

2. Setup:

- Place magnets or coils around the plant boxes, ensuring consistent magnetic exposure.

- For electromagnets, connect to a low-voltage power source and control intensity.

- Plant seeds in identical conditions, with one box as a control (no magnetic field).

3. Observation:

- Monitor growth rates, leaf size, and root development over 2-4 weeks.

- Record differences between magnet-exposed and control plants.

4. Analysis:

- Compare results to see if magnetic fields influence germination or growth.

- Discuss possible explanations, such as altered nutrient absorption or cellular activity.

This experiment is perfect for students or gardening enthusiasts curious about environmental science. Adjust variables like field strength or plant species for deeper insights!
