A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole is located?

The location of the poles of the magnet can be determined by suspending it freely. A freely suspended bar magnet always points in a north-south direction. The end that points towards the north direction is the north pole of the magnet, while the end that points towards the south direction is the south pole of the magnet.

  • A bar magnet is a rectangular piece of the object.
  • It is made up of iron, steel or any other ferromagnetic substance or ferromagnetic composite, having permanent magnetic properties.
  • The magnet has two poles: a north and a south pole.
  • When you suspend it freely, the magnet aligns itself so that the north pole points towards the magnetic north pole of the earth .
