Bar magnet and compass

Explore the field around a bar magnet and the direction a compass points.

Open the simulation

What to notice

Outside the magnet, magnetic field lines leave the north pole and enter the south pole.

Key relation

B ∝ magnetic moment / r³

Try this

Increase magnetic strength. Watch the arrows around the magnet.

What you can change

• Relative field strength: 0.5 to 3 ×
