Magnet
How strong does a magnet need to be to have any effect on a bean seed?
I am doing a science fair project and I need to find out how strong of a magnet to use. I am testing the effects of magnetism on a bean seed compared to a regular one. How strong a magnet do I need?
You can use neodmium magnets for this purposes.
