Their testimonies about the beneficial, sometimes miraculous effects from magnets are encouraging and shouldn't be discounted, yet fall short of scientific proof. Those who oppose the use of static magnets believe they're nothing more than medieval witchcraft revised for the '90s. Let's look at the evidence. The Science Behind Static Magnetics Unlike an electromagnet, which sends electrical current artificially through conducting coils to create the magnetic field, a static magnet has a built-in permanent magnetic field that never needs replenishing. Examples of static magnets are those used to stick notes to a refrigerator door, a grade-school horseshoe magnet and a magnetic compass.
All magnets have a north and south polarity and either attract or repel.
North repels north, north attracts south and south repels south. Reports indicate that through the magnets' natural effect on charged particles in the blood, they help blood vessels expand, allowing a larger quantity of nutrient-rich blood to flow into an area for faster healing and growth. Blood is an electrical conductor, and electrolytes are compounds that can carry electric current within the body via the movement of ions such as sodium, potassium, calcium and magnesium. When these ions with their positive and negative charges pass by a magnetic field, a separation of ions occurs. According to a recognized expert on biomagnetism, Ted Zablotsky, MD, new research over the past five years has pointed to three specific actions of static magnets on blood vessels.
