Magnets are very cool. Put them together one way and they’ll stick. Turn one around and they’ll push apart. But did you ever really play with two strong magnets and think about it?
Get two strong magnets. Some Radio Shack and hardware stores have nice ones that are about an inch wide, two inches long, and under a half-inch thick. If you find them, buy several as they’ll come in handy to hold papers on the fridge!
Hold a magnet in each hand and bring them together so they repel each other. Feel the way they move as you gently feel the springiness between them and understand that you’re feeling an actual invisible force field!
Science fiction writers have talked about force fields for decades but, really, that’s exactly what you have in your hands.
There are many experiments to do with magnets and we’ll look at a lot of them here in future posts.
In the meantime, keep your eyes open for strong magnets!
