Areion devices produce a high-intensity electromagnetic field of 3 Tesla that can go deeply in the body to modulate the nervous system. Compared to typical bar magnets, the magnetic field initiated by these devices is approximately 500 times more powerful, due to which it has the capability to traverse through garments and cartilage. It functions by delivering small electrical impulses to the affected muscles. This feature makes it a useful tool for physiotherapists for effective pain management in patients.
