What it practises

Solving a puzzle quickly is not the same as understanding why it works — the debrief step covers that.

Quick lesson: Magnetic fields

A magnetic field can be drawn as lines. Magnetic fluids line up along those field lines, which is why they form spikes near a pole.

Check question

Outside a bar magnet, field lines point…

Answer: From north to south. By convention, field lines leave the north pole and enter the south pole.
