With magnetic therapy – Is bigger always better? Is stronger always superior?


Using a big hammer to tap in a small tack is not the best tool for the job, so too the biggest and strongest magnet is not always the best option for pain relief.



Selecting the right device is common sense. Use the smallest devices (Q6-1.5 and QF10-2) for trigger points, acupuncture points and small joints such as fingers.

While for the lower back and larger joints such as hip pain and shoulder pain use the larger devices QF28-6 and QF28-3 which penetrate much deeper and capture much more of the tissue with the magnetic field they project.

See the online manual or go to the Body Chart and click on the relevant body part for recommended devices and placements. If you’re still unsure, contact us with your specific condition and we’ll make a recommendation based on medical evidence and thousands of patients treated.

The research has shown that magnets can also be too strong to have an effect. Obviously they can be too weak to have an effect, but not many people realise they can sometime be too strong. For instance…

Two studies illustrate the point (see references below). One by Morris showed that the application of a 10 or 70 mT static magnetic field resulted in a significant reduction in tissue swelling, but a magnetic field much stronger at 400 mT had very little effect. In another study (Okano), the opposite occurred, that is the weaker magnetic field had no effect.

There seems to be what’s known as a window of effectiveness. It’s like Goldilocks and the three bear – has to be just right!


What’s more, because Neodymium magnets are so powerful, there comes a point where they become dangerous. Aside from getting stuck to things that take super human strength to pull them off, if two large magnets (say 5x5cm or 2×2 inches) snap together, they can literally smash fingers and break bones!

So bigger and/or stronger does not necessarily mean better.
