Abstract
The distorting effect of a ferromagnetic disk of finite dimensions on the constant field of a magnetic dipole is considered. It is shown that, depending on the mutual arrangement of the dipole and disk, the dipole field may be both intensified and attenuated. It was proposed for the first time to use an additional ferromagnetic disk in order to attenuate the shielding effect of a ferromagnetic disk on a dipole field. The theoretical considerations were confirmed by the experimental results. The presented information can be useful when organizing testing of the magnetic fields of objects that are placed behind a ferromagnetic obstacle.
