How Do Medical Magnets Work?
Is It Just the Placebo Effect?

Some magnets are multipolar, with both the north and south poles facing the patient/desired body part, often with manufacturers touting that their circular or checkerboard or triangular pattern is in some way superior. But this also further limits how far the magnetic field reaches. Any effect inside the body must be limited to a few millimeters, only skin deep.

Possible Causes of Action

Magnet marketers prefer to advertise that they work by using testimonials, so as not to make any unsupported claims. The most common causes of action claimed is an increase in blood flow, supposedly attracting the iron atoms in the hemoglobin in blood or the water ions in the blood and tissues. Other claims are that nerve impulses are altered, reduced acidity of the bodily fluids, and increased oxygen in the tissues.

Mythbusting Magnetic Theories

Because of the multipolar design of most magnets and the extremely limited penetration of the tissues even by those of high Gauss ratings, any effect inside the body would be negligible and no more than skin deep. Rather than being attracted to magnetic fields, blood and water are actually weakly repelled by magnets.

Real Relief, But...

Magnets work for many people, but not because of their claimed magnetic effects. The real cause of the cure is that the patient believes something is being done, and this stimulates the body to feel less pain or fatigue. This placebo effect is seen in medical studies for most diseases, with 10-60% of the people in the control group - those given an inactive "sugar pill" or sham treatment, having a positive response. This is especially true with the relief of pain and fatigue.

People who experience relief from pain using magnets or any other treatment have real pain relief. For that reason, I would not discourage or belittle those who have found their cure in using this treatment, but rather I celebrate their relief, no matter that is is placebo effect rather than magnet effect.

Double Blind Studies Show the Truth

In medical studies done properly, a treatment is given in a double blind fashion with half of the participants getting the proposed cure and half getting something that looks exactly like it but has no active ingredients - and neither the patients nor the researchers know which group received which.

In most studies, both groups will have a significant number of people who report an improvement in their condition due to the placebo effect. It is only when the group with the proposed cure has significantly more people reporting an improvement than the control group with the inactive ingredients that the proposed treatment is shown to be effective.

Placebo Effect Generates True Testimonials

The placebo effect is a reason why the testimonials used in advertising are easy to find and the people giving the testimonials have truly felt relief from their suffering when using the treatment. It is also why these need to be taken with skepticism towards the advertised product.
