Effect of Magnetic Fields on Radish Seed Germination

This experiment by Natalie Hyland in Grade 12 at Oakland Catholic aims to determine the impact of magnetic fields on radish seed germination. Using Iron-Neodymium-Boron permanent magnets with specific magnetic properties, the study observes the growth of radish seeds in controlled conditions over 8 days, repeating the experiments three times to gather reliable data.

  1. Effect of Magnetic Fields on Radish Seed Germination Natalie Hyland Grade 12 Oakland Catholic

  2. Objective • To determine the effects of magnetic fields on radish seed germination

  3. Hypothesis • Seed germination will be inhibited by the presence of magnetic fields

  4. Materials • 12 Iron-Neodymium-Boron permanent magnets • BHmax:42 Mega-Gauss Oersteds • Surface Field: 2250 Gauss • 4 petri dishes • 80 radish seeds (raphanus sativus) • Digital camera • Water • Paper towels • Double sided tape

  5. Iron Neodymium Boron Magnets • Fe-Nd-B magnets are among the strongest permanent magnets in the world. • Composition is 82 atomic % Fe, 6 atomic % B, 12 atomic % Nd) • Purchased from K&J Magnetics • BHmax:52 Mega-Gauss Oersteds • Requires roughly a 19 pound force to separate two magnets

  6. Procedure • Cut paper towels to fit inside 4 petri dishes • Set petri dishes by a window at room temperature • Saturate paper towels with tap water • Place 20 radish seeds in each petri dish • Observe growth/germination each day • Moisten paper towels if necessary • End trial after 8 days • Repeated experiments 3 times

  7. Experimental Setup Control Petri Dishes Fe-Nd-B magnets

  8. Trial 1 Data

  9. Trial 2 Data

  10. Trial 3 Data
