Tuesday: Poles, Pull and Push

Rocket holds two magnet toys. He pushes them together. Snap!

He flips one over and tries again. They slide apart.

"Hey! Now they will not touch," he says.

Raven leans in. "What do you notice about the ends?"

Nova hums. "Every magnet has two ends. Try each end."

Two poles

One end is the north pole.

The other end is the south pole.

The pull is strongest at the poles.
