Polarity Playground

Magnets exert a distance-dependent force: material determines whether an object responds, pole orientation determines attraction or repulsion, and field maps represent direction evidence sampled around magnets.

What your child will figure out

  • Test deceptive materials and distinguish magnetic response from surface appearance.
  • Predict attraction or repulsion from the poles that face each other.
  • Gather evidence that magnetic interaction becomes stronger as distance decreases.
  • Infer a field-direction map from several compass samples and transfer pole reasoning to a permanent-magnet puck maze.

The levels

  1. Force table

    Freely move a magnet, then test painted steel, shiny aluminium, copper, and wood using motion only.

  2. Pole puzzle

    Rotate a bar magnet and predict attraction or repulsion from the two facing poles.

  3. Distance dial

    Compare the same pole interaction across distances with force arrows added.

  4. Compass survey

    Collect six local compass directions before revealing a joined field-direction map.

  5. Puck maze

    Guide a clearly labelled permanent-magnet puck through three gates without a field-line overlay.

Ready when they are.
