Does the shape of a magnet affect its magnetic field?

A:
Yes, the shape of a magnet will affect its external field.  For example the shapes of the fields of horse-shoe shaped magnets and bar magnets are quite different. You can do an experiment at home using iron filings sprinkled over a sheet of paper and holding a magnet underneath. Various configurations of magnets are used in high energy accelerators to bend (dipole magnets) and to focus (quadrupole magnets) the circulating beams.  See the web site: 
  for an example.
