From a white paper by Ben Philipson, the inventor of the Curatron Systems.
Only Pulsed electromagnetic fields (PEMF) influence cell behavior by inducing electrical changes around and within the cell
The magnetic field strength of a magnet is related to its size and composition, which determines the depth of penetration of the magnetic fields. There are many therapeutic systems on the market which use permanent magnets made of different materials. These manufacturers often claim field strengths of 4,000 gauss and higher. These values are however not relevant at all, since the measured field strengths of these magnets range from 310 gauss to 2,200 gauss at the surface, at 1-inch distance around 10 Gauss at 3-inch distance absolutely nothing! 
To obtain any electrical induction at all, permanent magnets have to be mechanically moved. Static magnetic fields do not cause any electrical induction! 
Pulsed electromagnetic fields (PEMF) influence cell behavior by inducing electrical changes around and within the cell. Improved blood supply increases the oxygen pressure, activating and regenerating cells. Increased calcium transport stimulates the repair of cartilage.
In order to obtain a real therapeutic effect the induced field strength has to be sufficient to penetrate deep inside the body. This condition can only be met if the electromagnetic flux generated at each individual coil is in excess of 100 Gauss (10 milli-Tesla).
Battery operated systems for whole body use are unable to generate these necessary multiple high energy electromagnetic fields simultaneously, at each individual coil, since the battery would be empty in just a very short time.
This technology has undergone many scientific clinical trials world-wide. Hundreds of thousands of people have experienced the benefits of pulsed electromagnetic field technology. Are you going to be one of them?

Just wondering, if this is true
How do I know that the effect will be real and not just placebo?
Most scientific clinical studies clearly show that in order to obtain clinical relevant results the minimum pulsing field strength must be at least 3-5 milli Tesla (30 to 50 Gauss).
In order to generate piezoelectricity inside bone and cells the field strength must exceed 10 milli Tesla (100 gauss).
There are different variations of large and expensive coil systems mounted on arms or beds, but none of these systems is able to generate energies higher than 100 gauss.
So, if this is true, what effects can the 2000 HT, on the low settings, have on one’s health. According to this, the 2000 HT is under powered to have any effect to do anything.
The low settings are there on the 2000HT so as to match or come close to the very low values found on competing systems. There are a few customers out there that simply do not believe that energy levels higher than a gauss or two are safe or necessary. When we introduced the 2000HT, it was so we could say “me too” when one of the low magnetic flux density machines was seen by the customer as the the machine they wanted. At the time I thought the factory was nuts to do this but the die was cast. Looking back it was good decision, we’ve sold a lot of systems to folks who wanted low magnetic flux density and most of them use the five high power programs because the five low energy programs do not help with pain, arthritis, sciatica and other primarily joint issues.
I do believe that there are people who are ‘healed’ because of the placebo effect. Our higher power systems also help dogs, horses and others.
I have a couple of site errors that we are working with for the testimonials but this should help a litle.
I doubt dogs and horses can have what we humans see as the placebo affect.
Thanks for posting!
