WHAT’S HAPPENING?
HERE'S HOW
1. Stack the ring magnets one on top of
one another on the stand. Be sure that
all the repelling sides are facing each
other, so all the magnets end up
hovering in the air.
2. Push down on the top magnet a little.
What do you observe?
3. Now carefully remove the top ring
magnet.
What happens now?
Hovering
magnets

Even the very first ring m
agnet
will hover freely a few
centimeters up in the a
ir. All of
them will end up hover
ing above
one another, as if held u
p by an
invisible hand.
When you push down o
n the top
ring, the lower ones wi
