A NZ company "Biomag" sell wool underlay products which have embedded magnets which are said by them to impart all the marvellous things that people claim that magnets impart. (These usually tend towards being all the things you could reasonably or unreasonably hope may be caused by some marvellous science based* effect while you slept. (* benefits measureable, quantifiable, repeatable, ...) Whether any of the hoped for effects genuinely occur is both tbd and extraordinarily unlikely. Alas. Biomag at some stage added magic magnetic healing bracelets to their product line. In June a decision by the NZ advertising standards committee suggested that they were being naughty and would they please scrap the ads. Another recent similar decision means that as of right now they make little or know mention of magnets or claims for their efficacy. Odds are this will not last.

A: Yes, some can in some ways. Q: Do any of the permanent magnet healing or positively bio-acting permanent magnet based devices do what they claim? A: Conceivably some product somewhere might, but for practical purposes any "magnetic healing" device sold is either a con job or sold by the well-intended- self-deluded. Some effects or claimed effects are self-excluded from assessment using 'the Scientific Method' [tm] and people get pointlessly exercised demanding that such should 'follow the rules'. For such that do not work that way you instead use the rules that they demand, or you go and examine something else - these are not the affects you want, nothing to see here, move along. However, magnetic healing / pain relief /general vitiation is not included in such an exclusion. If they work at all they use forces of nature and are measurable, quantifiable and able to be assessed 'scientifically'. No such claimed effects of permanent magnets have ever survived the test of double blind scientific study and peer review. Countless claims are made. People offer eg "money back if not satisfied" , which may sound like it guarantees the product must work. Alas, human nature ensures it doesn't. Any number of product that do little or nothing and that have full money back guarantees still make money for the sellers. Sadly.
