Q Magnets are a magnetic field gradient generating medical device and provides the user with an optimized design based on extensive research and feedback. Even so, the magnetic field of a static magnet dissipates very quickly and the effect is highly localized.  If you do not select the right Q Magnet model for the right target tissue, then there is very little chance of a therapeutic effect.

So selecting a magnetic device with an optimised design, with the right field characteristics and placing them correctly so that the penetrating field envelopes the offending target tissue are variables requiring the correct answers otherwise there will be very little effect.

If a physiological target for instance is beyond the reach of a device, it is unreasonable to expect a therapeutic effect.The experience to make the right decisions can be made through much trial and error or through training by experienced health professionals who have already had much practice.A more detailed explanation about specificity in the practice of neuromagnetics can be found here.
