Magnetism Basics
Understand that a magnet can attract or repel other magnets.
When you bring two magnets close, they will either stick together or push apart.
Magnetic Materials
Know that magnets only work with iron or metals like nickel and cobalt.
My magnet won't stick to this copper coin because it's not a magnetic material.
Magnetic Poles
Every magnet has two poles: north and south, which are opposites.
The north pole of one magnet will be attracted to the south pole of another.
