Magnet therapy is based upon the idea that magnetic fields have the ability to help the body heal or simply relieve pain. Most often, pseudoscientific support is offered by claiming that magnets affect the iron in our blood, but that iron is non-ferrous, which means that it does not react to mangetic fields!
Moreover, many of the magnets you will find used in magnetic therapy are of the same type used with refrigerator magnets. But these magnets aren't even strong enough to have an affect through the thickness of our skin, much less the various pouches they are typically held in. At just one centimeter from such a magnet, the magnetic field is measured to be one Gauss - the strength of the Earth's magnetic field. In other words, when such a magnet is one centimeter away from something, it has no more effect than the Earth's own magnetic field is already having. Needless to say, there is no reliable, repeatable, controlled scientific evidence that magnets have any medicinal value.

What is Alternative Medicine?
There's an awful lot in the news and in society about "alternative medicines" these days. By some estimates, it's an industry doing between $15 and $20 billion annually - and growing! But what is alternative medicine - how does it differ from scientific medicine and why do people use it?
Skepticism & Critical Thinking
This is the main index for issues dealing with skepticism, critical thinking, logic and arguments. The first section is Critical Thinking itself - how to think about claims and arguments you hear, how to critique arguments, and how to formulate your own arguments such that they are more likely to be sound and valid. The second section is about Skeptical Investigations - the practical application of the critical thinking skills covered in the first section. Here you will find critiques of things like astrology, alternative medicine, parapsychology, the New Age and more.
