As you'll find, atoms are magnetic. Everything is made of atoms. The nucleus of a hydrogen atom is magnetic. Water is mostly hydrogen. We are made up of mostly water. See the connection?

If you'd like to read about some magnet therapy studies go to www.therionresearch.com. They have dozens of them on their site. Healing With Magnets, by Gary Null, has plenty of studies in it too. There are other books on magnet therapy with even more studies in them.

The point of my posts was to let people know that there is scientific evidence supporting magnet therapy. If you're curious, look up more information yourself. If you're convinced you already know the answers without having spent any time researching it on your own, then don't. Just be sure to explain that kind of "critical thinking" to your students.
