Many people wear small magnets for pain.
Now the same theory is being used on a larger scale in Tucson, Arizona.
A new research clinic is offering magnetic therapy.
The clinic in Tucson is one of only seven in the country.
Doctors say magnetic molecular energizing can heal injures and broken bones faster than your body can.
It also offers hope for untreatable diseases.
One patient who spent 40 hours under a powerful magnet says he now feels something he has not felt in 10 years...his feet.
Treatment costs about $50 an hour.
Magnetic therapy is in the last phase of FDA approval and is under review, and thus still considered experimental.
