Over the last century, engineers and scientists have developed magnets out of various materials which produce a much stronger magnetic effect than those made of steel. Today, many magnets are made of ferrite (ceramic) and neodymium-iron-boron - which is 100 times stronger than steel. These advancements have also brought about resurgence in the popularity of magnetic therapy for pain, particularly in North America, where the magnetic therapy industry boasts annual sales of $300 million in the U.S. alone.

Magnetic therapy devices come in such forms as magnetic bands, patches, cushions and jewelry. They are placed over the joints and muscles to achieve everything from back pain relief to carpal tunnel treatment. There are also several organizations and institutions dedicated to the study of magnetic therapy, such as the Bio-Electro-Magnetics Institute, and the North American Academy of Magnetic Therapy.

Professional athletes, such as tennis players and golfers have also begun to use magnetic therapy for pain. Products such as magnetic back pads, bracelets and cushions can often be found in professional sports stores.

In addition to humans, magnetic therapy has also been used on animals such as

racehorses and even llamas. Custom-made pads and cushions have been specially suited to fit the animals and provide therapy for their joint and muscle pain.
