Principle

The pupils learn that

  • magnetic forces also act when a magnet and an iron object are not in contact.
  • the magnetic force increases with decreasing distance.
  • the magnetic force depends on the size of the attracted object.
  • the magnetic force can pass through materials which themselves are not attracted by magnets. 

Benefits

Quick and easy experiment for qualitatively understanding of magnetic phenomena

Tasks

To investigate if objects can still be attracted when they are not in contact with the magnet.

  1. To investigate what the strength of a amgnet depends on.
  2. To investigate whether a magnet can also have an effect through a non-magnetic object.
