The steel spheres in the Newton's Cradle I have are now magnetized be
being too close to a powerful magnet. While this produces some
interesting variations of the cradle's normal operation, I would prefer
non magnetic spheres.
Is there a convenient way to demagnetize a sphere?
Thanks, David Abineri
