why does a magnet have a north and a south pole
Asked by 2joseph | 22nd Jul, 2009, 05:22: PM
In a bar magnet, the molecular magnets are alinged in the same direction i.e. the north-poles of of all the molecular magnets point in one direction, while the south-poles in the opposite direction. Hence, one end behaves as a strong north-pole and the other end as a strong south - pole.
An isolated magnetic pole (north or south) does not exist.
