Snapling — Poles: Attraction & Repulsion Polarity Bridge

Hi!

I'm Snapling.

Welcome to Polarity Bridge!

Will you help me investigate poles: attraction & repulsion?

The Grumblies have mixed up our clues.

Let's check the evidence!

Magnets have north and south poles.

Like poles repel and unlike poles attract in a simple bar-magnet model.

Which pair attracts?

  • A. North facing north
  • B. South facing south
  • C. North facing south

The answer is C: North facing south

Our bridge model places north facing south to pull the pieces together.

North facing north pushes them apart.

The labels let us decide without relying on color.

That clue helps us make sense of this place.

Turning one magnet changes which poles face each other.

The force can therefore change from attraction to repulsion.

Which pair repels?

  • A. North facing south
  • B. South facing south
  • C. South facing north

The answer is B: South facing south

Our bridge model places north facing south to pull the pieces together.

North facing north pushes them apart.

The labels let us decide without relying on color.

Hmm...

how does that connect to our first clue?

Our bridge model places north facing south to pull the pieces together.

North facing north pushes them apart.

The labels let us decide without relying on color.

How can the model change from repulsion to attraction?

  • A. Turn one magnet to face unlike poles
  • B. Only repaint both labels
  • C. Move the labels without turning the magnet

The answer is A: Turn one magnet to face unlike poles

Turning one magnet changes which poles face each other.

The force can therefore change from attraction to repulsion.
