Prior knowledge & experience:
Gravity pulls objects down.
Explain why the discs are "floating".
The alignment of the magnet creates a magnetic field with a north and
south pole: north poles are attracted to south poles, but like poles
Magnetism is derived from the movement of electrons. Two north poles or two south poles will invariably push against
each other. So the very force that causes magnets to be attracted also
causes like magnets to push against each other.
"Floating" is impossible because gravity pulls all objects down.
