in accordance with previous discussions , one of the functions of an applied magnetic field is the amelioration of pain through the use of the lateral displacements of electrons caused by the hall effect , in which the flow of electrical impulses are shifted 90 arcuate degrees with respect to an orthogonal magnetic field . as previously cited , this is merely one of the many effects that arise upon the application of a magnetic field to the living tissue . consequently , since the hall effect is a direct derivation of faraday &# 39 ; s right hand motor rule — one solitary pole of 2 magnets can be used for such therapy , since meaningful deflection of a pain impulse from the normal path to the brain can only be achieved in such manner . a bi - polar , or the simultaneous application of a n - s magnet , only causes the electric impulse or pain signal to zigzag and consequently be allowed to return to its normal path . in order to fabricate a useful medical magnet therapy device the solitary or monopole face of a permanent magnet must be utilized . meeting such a requirement can be achieved through the use of a single permanent magnet or by 2 clusters or groups of permanent magnets configured in such orientation as to expose a predetermined pole of the magnet ( s ) to the tissue or region under treatment . while there are advantages to using a relatively large sized magnet in magnetotherapy , it is also desirable to utilize a plurality of permanent magnets mounted to a flexible material to allow the magnets to conform to the surface area under treatment . in accordance with the teachings as related above , fig1 depicts a magnetic therapy collar comprising of a flexible strap ( 10 ) with permanent magnet ( 20 ) suitably attached to the flexible strap ( 10 ). the solitary permanent magnet has a predetermined face of the magnet ( 20 ) attached to strap ( 10 ) as to present the desired pole to the tissue or area to be treated . a counterweight of sufficient mass ( 30 ) as to provide orientation of permanent magnet ( 20 ) is suitably attached to strap ( 10 ). a magnetic device in accordance with the teachings of the device as depicted in fig1 in which a solitary or plurality of magnets are attached to the flexible strap ( 10 ) and whose strength can be increased by the addition of like permanent magnets ( 20 ) and secured through magnetic means . in fig2 the flexible strap ( 10 ) consists of a tubular material , and consequently a permanent magnet placed within the tubular structure is free to longitudinally move within the structure . a permanent magnet ( 20 ) in place on the exterior surface of the tubular strap and through the friction and magnetic attraction between the magnets become attached to a desired position on the strap ( 10 ). similarly , additional magnets ( 20 ) can be placed over the existing magnet ( 20 ) residing within the tubular strap . the stacking of additional magnets ( 20 ) increases the effect power and penetration depth of the magnets utilized for therapeutic purposes . with respect to fig1 and 2 , a fastener ( 40 ) is used to secure the ends of strap ( 10 ) in such a asliion as to render it useable as a collar . such fasteners such as , but not limited to , are reflected in the following examples : buckle , hook and eyelet , velcro - type , magnetic and polymeric means . in fig3 a magnet is secured via a clip ( 50 ) to an existing strap ( 10 ) or collar and similarly a counterweight ( 60 ) is secured via the clip ( 50 ) to an existing strap or collar . this allows component retrofitting the therapy device to an existing collar or strap .
