Owning an acrylic spa or hot tub from Presidential Pools & Spas, manufactured by Master Spas, can have numerous health benefits. One of those benefits, Bio-Magnetic Therapy, is used by doctors, athletes, and physical therapists across the world for a variety of treatments. For residents across Arizona, every Master Spa comes with the patented Master Force Bio-Magnetic Therapy system. 

How It Works

Bio-Magnetic Therapy works by using magnets to balance the electromagnetic forces that are prevalent throughout the human body. The electric forces exist to help maintain the body in different ways. They can send information and transfer nutrients, among other things.

When a cell is injured, its electric forces are reduced, resulting in a low Zeta potential and therefore inefficient ability. For a cell to get back to normal strength, its Zeta potential and electromagnetic functioning has to be restored. Bio-Magnetic Therapy can be applied to an injured area to improve its Zeta potential, regulate electromagnetic functioning and help the body heal itself. Our Master Spas comes with a patented Master Force Bio-Magnetic Therapy system that can be used on various parts of the body.


Magnetic healing has existed for thousands of years dating back to ancient China. Eventually, it was understood that magnets can also attract the Iron found in human blood. When applied, the magnet can increase blood flow to a specific area and create a feeling of euphoria similar to exercise.

Common Uses

Bio-Magnetic Therapy has many uses. It has been known to be able to help treat arthritis, migraine headaches, and injuries to ligaments, tendons, and muscles. It can also improve circulation, relieve pain, and ease stiffness.
