A:

Hello Shanzeh,

The field of a bar magnet is that of a classic dipole field.  The field is actually the strongest inside of the magnet. Figure 1 shows the theoretical lines of magnetic field.  Figure 2 shows the alignment of iron filings sprinkled on a sheet of paper right above the magnet.  They align closely with the theoretical field lines.
