23 If these claims are accurate, there should be a measurable temperature change within the tissues during magnet application.Īlthough therapeutic magnets have been suggested to increase blood flow by increasing tissue temperature, this phenomenon has not been documented experimentally. Additionally, manufacturers claim that their products' magnetic fields have the ability to penetrate tissue more deeply and more safely when compared with other deep heating modalities such as ultrasound or diathermy. If magnets do, in fact, increase temperature and therefore blood flow, they may be effective as a thermal modality. However, the usefulness of these magnets as a thermal modality able to produce clinically significant temperature changes has yet to be examined. Many allied health professionals, as well as many professional, collegiate, and recreational athletes, use these magnets. Most are constructed of rubber impregnated with a magnetic material and induce low-level, static magnetic fields with a field strength of approximately 0.1 T (1000 G). Today, commercially available “therapeutic” magnets are essentially small sources of magnetic fields. To date, few investigators have examined whether magnetic fields alter blood flow in vivo. In an effort to support their claim that magnetic fields caused vasodilation, magnet vendors reference the work of Pratt and Mishra, 21 which was presented at a symposium but has not been subsequently published. Pratt and Mishra, 21 in work with saline solution and glass tubing, suggested that an ionic solution had greater flow in the presence of a magnetic field than in the absence of the field, independent of the diameter of the tube. In addition to potential vasodilation, blood flow may be altered by another means. This migration against resistance may cause the production of heat that, in turn, would result in blood vessel dilation.
22 The movement of these particles is resisted because the particles are forced to accumulate against their normal direction of flow. The magnetic field–induced voltage produced by this accumulation of charged particles against a concentration gradient is known as Hall voltage. The charged particles in blood may, in the presence of a magnetic field, accumulate toward like poles. The Hall effect is an electromotive force that causes charged particles to accumulate with like charges in the presence of a magnetic field. The theory behind the use of magnetic fields to increase blood flow stems from the physics principle known as the Hall effect. Touting information from unpublished studies, 5, 20 magnet manufacturers and distributors have claimed that magnetic fields are associated with an increase in blood flow. 1, 2 More recently, magnetic fields have been used in the treatment of musculoskeletal injuries, 3 – 5 nerve dysfunction, 6 – 9 pain, 3, 10 – 14 fractures, 15 – 17 and osteoarthritis. Here's a video of a woman taking part in the challenge showing that anything can stick to your skin, even if it's not a magnet.The use of magnetic fields to aid the body's healing response dates back to ancient Egypt and Greece. If you have come across the videos of magnets sticking to people's arms with claims that it is a result of a magnetic microchip and are worried that the vaccine will make you magnetic, do rest assured that it won't. We’re all bleeped,” except she didn’t say “bleeped” if you catch our drift.ĪLSO, SEE: Discovery Health COVID-19 vaccination sites This is the arm I got the Pfizer shot in,” while placing what appears to be a magnet on her left arm, according to Angelo Fichera writing for the website . She then continued to say, “You go figure it out. Photos and videos posted on social media show several people with magnets on their arms at the inoculation point followed by claims that magnets will stick to your arm after you’ve gotten the COVID-19 vaccine injected into that arm.įor example, a picture posted on Instagram and Twitter showed a woman saying: “Here’s the magnet. For the record, scientists have debunked the magnetic microchip theory and reassured us that a magnet will not stick to your arm due to the inoculation.
