Abstract: Based on the theory of molecular current hypothesis, the model of
the magnetic flux intensity at a point around the cylindrical magnet is
established, and a numeric method for the solution of the model is proposed.
Compared with the dipole model, this method doesn't need the precondition that
the distance from the magnet to the evaluation point is much larger than the
maximum dimension of the magnet. At the same time, a group of the parametric
values and experiment results are illustrated.
Keywords: Magnetic flux intensity, cylindrical magnet, dipole, numeric approach
