It is quite easy to predict the movement of a simple pendulum,
but what if it is influenced by the forces of magnetic
attraction and repulsion? In this exhibit a magnet is
made into a pendulum. A rotating table is underneath it
with three clusters of magnets, either opposite or like
poles exposed to the pendulum. The user turns the table
and let each cluster influence the movement of the pendulum.
Because the pendulum magnet is either being attracted
or repelled by the magnet clusters, the motion of the
pendulum becomes unpredictable and could go on moving
for a long time. This exhibit gives a practical demonstration
of how forces such as gravity, friction and magnetic attraction
and repulsion interact.
Magnetic
Pendulum is available in the "I AM a Scientist"
travelling exhibit package.
