Effect of Magnetic Fields on Radish Seed Germination Natalie Hyland Grade 12 Oakland Catholic
Objective • To determine the effects of magnetic fields on radish seed germination
Hypothesis • Seed germination will be inhibited by the presence of magnetic fields
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
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
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
Experimental Setup Control Petri Dishes Fe-Nd-B magnets
