Millions of people worldwide wear Neodymium magnets to promote health and wellbeing. We have found no evidence at all of detrimental effects of Neodymium magnets on people or animals – many people believe that magnets improve health and accelerate healing. These magnets are used to help relieve pain caused by conditions such as arthritis, back pain and carpal tunnel syndrome. These magnets should be fixed to the skin using surgical tape or sticking plaster, alternatively they can be sewn into clothing.

Our Neodymium magnets are commonly used in creative applications such as theatre design, clothes making, furniture making, exhibitions and packaging. They also have many uses in engineering and manufacturing where small size and maximum strength are required. What’s more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
