SUMMARY
The force exerted by an infinitely long cylindrical magnet on a magnetic dipole is determined by the magnetization vector, M, which is aligned in the z direction. Due to the infinite length of the cylinder, there is no external magnetization present outside the cylinder, confirming that the magnetic field is confined within. The discussion suggests that calculations may vary with different lengths of the cylinder, but the primary conclusion is that the external field remains zero.
