The speed of induction of pulsed electromagnetic fields into the body is an important factor for successful penetration of the energy deep into the cells and bones.
When we have electromagnetic energy available and we induct it too slowly into the body, the changes the magnetic energy is able to trigger are minimal. The best example to demonstrate this are the MRI (Magnetic Resonance Imaging) machines in hospitals, which are used to make computer generated images of specific parts inside the body.
These machines have electromagnetic coils inside -similar to coils of PEMF systems- and these coils are pulsed with very high speeds to obtain a very fast speed of induction (called "slew rate" for MRI machines). These speeds are directly responsible for the quality of the computer generated images. As a general rule: the higher the "slew rate" the better the image quality.
If you happen to know people who had an MRI exam and you ask them how it was, they will tell you that a constant very loud noise was heard during the examination. This noise occurs when large electrical currents are pulsed into the coils inside the MRI machine, which cause them to move in the same rhythm as the electromagnetic pulses resulting in the loud noise.
The same happens for the fast pulsed magnetic energy transferred into the body, which is called induction of energy. The faster the pulses are inducted into the body, the deeper the penetration and the better the results.
The electronic time 'window' of the Parmeds devices, during which the pulsed electromagnetic energy is inducted into the body, is controlled by a very fast electronic switch. In addition, the quantity of readily available PEMF energy for the professional models, combined with even faster speed of induction thanthat of the home device, makes these devices absolutely superior in the market.
