ABSTRACT:
A method is provided for focusing magnetic fields, reducing magnetic fields and shielding animate or inanimate subjects from magnetic fields. Further a media which has been subjected to a shielded or focused magnetic field is applied to a subject, as for example, topically. The method, in part, interposes between the subjects and the source of a magnetic field, at least one second magnetic field disposed in such a manner that the polarity of the second magnetic field cancels or at least partially neutralizes the magnetic strength of the first magnetic field. The second magnetic field can also be disposed so as to permit only a portion of the first magnetic field to escape shielding and thereby focused in a predetermined direction. Devices which normally emit magnetic energy and containing the shielding of the present invention are also provided.
