What else makes you wonder?

Why does a compass needle turn when a magnet comes near?

A compass needle sits on a tiny pin so it can spin freely — what could be tugging on it from very far away?

If every cut makes smaller two-ended magnets, how small can the pattern continue?

Imagine the cuts getting smaller and smaller — is there a smallest piece that still has two ends?

What extra guide could keep repelling magnets from sliding sideways or flipping?

A pushing magnet keeps sliding out sideways — what could stop the sideways escape without stopping the lift?

The short answer

Every whole magnet has two pole types. Matching facing poles repel, while different facing poles attract. Flipping one magnet swaps which pole faces the other, so the same pair can change from pushing to pulling.

Try this next

  • What changes if you widen the gap without turning either magnet? Predict the force direction first, then compare only how easy the force is to notice at several gaps.
  • Can you identify an unknown pole without trusting its paint color? With a grown-up and two large classroom magnets, compare the unknown end with one known pole and record whether it pulls or pushes.
  • What happens when a compass meets each end of one bar magnet? Keep the compass in one place, bring each bar end near in turn, and watch which needle end rotates toward it.

Now you — bend it

  • What if What if a repelling magnet could slide only up and down, not sideways?Separate the force direction you want from the directions that make the balance escape.
  • What if What if two different-size magnets show the same facing-pole relationship?Predict the direction separately from how strong the movement will be.

Can you prove it?Turning one whole bar swaps the facing pole without removing either pole. — Mark the bar’s two ends, turn the whole bar end-for-end, and check that both marks remain while their left-right positions exchange.

Design your own test:Keep the facing poles fixed. Predict whether widening the gap changes the direction, the noticeable strength, or both.

Explain it to a 6-year-old: Every magnet has two different ends: matching ends push, and different ends pull.

The whole story

How it works

A bar magnet has a north pole and a south pole. The force direction depends on the two ends that face across the gap: north facing north or south facing south pushes apart, while north facing south pulls together. The effect becomes much easier to feel at a small gap.

What people get wrong

A magnet is not simply sticky. It can attract or repel another magnet without changing material or strength; turning one complete bar changes the facing relationship. Color is only a label used to keep the pole types straight.

The catch

Attraction makes useful latches and holders, but strong magnets can pinch. Repulsion can make a low-contact spring or guided bearing, but a freely balanced magnet usually slides or flips unless something stabilizes it.

Questions kids ask

Why does flipping one magnet change the force direction?

A flip brings the magnet’s other pole to the facing side. That changes a matching pair into a different pair, or a different pair into a matching pair.

Which magnet poles attract?

Different poles attract: north and south pull together. Matching poles repel: north with north or south with south pushes apart.

What happens if you cut a magnet?

Each piece becomes a smaller complete magnet with both north and south poles. Cutting does not free a single isolated pole.

Why is magnetic force harder to feel far away?

The interaction weakens quickly as the gap grows. The pole relationship still sets pull or push, but the cue can become too faint for your hand to notice.

Are small magnets safe toys?

Tiny magnets can cause severe internal injury if swallowed and should stay away from mouths, noses, ears, and unsupervised play. Strong magnets can also pinch; use them with a grown-up.

Talk about it

  • Ask your child why the same two complete magnets can change direction after only one bar turns.
  • Before opening the explanation cards, ask what cutting, distance, or sideways motion might complicate.
  • Name a real job where attraction helps and another where guided repulsion could help.

For grown-ups

Permanent magnets are dipoles with north and south poles. Force direction depends on orientation; magnitude depends on separation and geometry. Cutting a bar creates smaller dipoles rather than isolated poles, and passive free-space levitation is generally unstable without additional constraints or materials.
