fun with magnets

a substance that attracts iron , cobalt and nickle is kown as magnet. there can be natural magnet as well as artifical one.

Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet's north pole and end at the south pole. When most people think of magnetism, they think about the magnetic force experienced between two magnets.

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. ... Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
