BIOflex® magnets feature a series of concentric circular poles. The circles are of variable width and alternate between the N and S poles. According to the Hall Effect, a magnet can optimally manifest its effects on the current carrying conductors of the body (e.g. blood vessels and nerves) when the currents cross the poles at right angles. Studies at major universities have verified that the BIOflex® magnetic design of concentric circles of alternating polarity not only causes an increase in blood flow but it can also relieve pain. The magnets act like an electric heating pad to bring more blood to an area, increasing the nutrients and building blocks the damaged tissues need to rebuild themselves. It also accelerates the clearance of toxic waste products of the injury. Like electric stimulation which can block pain signals, BIOflex® products manifest the principle of Faraday's Law that describes how a DC electric field is created as blood vessels pass through properly oriented magnetic fields.
