"Web1 Answer. Sorted by: 5. Because there are no magnetic charges the simplest system that can generate a magnetic field is a dipole. The field from a dipole (magnetic or electric) falls off as 1 / r 3 rather than 1 / r 2 so the field strength falls off more rapidly with distance than the electric field from a point charge.
