Magnets behave in surprising ways when you put them
together. To see how magnets react together; rest two needle-magnets
(see Make Needle-Magnets Experiment) on small pieces of paper in a
bowl of water. Watch how they pull and push.
Steps:
1. Place each needle on a pieces of paper and float them side
by side (with one point and one eye next to each other. What
happened to the needles?
2. Next, place the needles so that both eyes are side by side.
What happened this time?
Magnets have two ends (or poles). If you put
the poles of two magnets together, they will either pull together
or push apart. Magnets will pull (attract) each other if the
poles are different. This invisible pull is called a magnetic
force. Magnets
will push (repel) each other if the poles are the same. This
magnetic forces pulles against you.
