When Enviro-Tech first began marketing magnets for health usage back in 1985 we were somewhat ahead of the wave and our products were viewed with a degree of curiosity, if not incredulity. Now it seems there are magnet sales companies on almost every corner (either really or 'virtually' on the internet). Many of these companies seem less well informed than those to whom they sell.
We offer what we believe to be not only the most comprehensive selection of magnets and products but also a very good choice of books and articles on the effects and usage of magnetic products; from theory to practical application. We also make a point to teach everyone that wants to learn, everything there is to know about magnets; how they work, what they are made out of, where to use them, when to use them, and how they will help. We believe the key thing that is missing in the magnetics marketing and manufacturing business today is education, and we can help solve that problem.
One of the major failures of many magnetic products on the market today revolves around their lack of strength. The Polar Power (TM) brand emphasizes maximum strength for intended useage. We utilize several types of magnetic materials in our line of products.
The strength of magnets is usually described either in gauss or tesla units - 1 tesla is equal to 10,000 gauss - these are measurements of magnetic flux (or force), or more specifically the density of the lines of magnetic flux. Measuring magnetic strength is usually done with a magnetometer or a gauss meter. The strengths of magnets can be related in more than one way and this can cause confusion at first. Relating strengths in more than one way can actually be an advantage if you understand the difference.
One reference is to relate the manufacturers rating. This is expressed as Br - residual gauss or a "closed magnetic circuit" value. This is great to compare one type of magnetic substance to another but it can leave you guessing about the field strength at any given distance because this type of rating is not size dependent. Many marketers like this reference because it tends to sound stronger (the numbers are bigger). Another method is to relate the surface gauss strength; if the size is given also then this is useful. The best information on strength comes when one is given strengths at measured distances. That way one can know the magnetic field strength where it is needed, which is usually some distance away from where the magnet is placed.
You will find a chart relating strengths of many of our products at measured distances (which results in their depth of penetration) on page 6 of our catalog, or at the link on the bottom of this page.
The products we produce have a very wide range of usage, from the very small to the very large, from weak (magnetically) to very strong. Nearly everyone, young to old, can enjoy the benefits of what these products have to offer.
Questions are often asked, relating to the use of magnetic products having 'bipolar' or 'multipolar' (both north pole and south pole fields on the same surface of the magnet) field arrangements. Usually these are flexible and rather thin. Our research and experience shows at best a limited value in the use of multiple pole configurations, and usually many disadvantages. The greatest difference of 'straight' or single pole (one single pole on each side) magnets is their ability to project a relatively strong field at greater distances than multiple poled products (this involves the depth of penetration issue). Our products that have multiple magnets in them have all the same pole facing the same direction and are arranged to provide an even field at the proper treatment distance. These products (with multiple magnets) have the advantage of a greater spread of field lines than a single magnet of the same type and overall dimensions.
We have also noticed a great degree of confusion exists in the market when a customer wishes to buy a magnetic bed pad. Customers frequently do not know the correct questions to ask concerning the magnetic properties of the bed pad. If the customers ask logical questions can they trust the answers that are given to them? Does the seller even know anything about the product that he is selling?
In general you should get a bed pad with a negative field of use, having as many magnets as possible, that are evenly spaced. The pad weight is usually a useful rule of thumb in choosing this type of product. If two twin sized pads of equal dimensions have significantly differing weights you can pretty well assume the heavier pad will have either larger magnets, more magnets, or both. Therefore the bed pads that are heavier, either have more magnets or have larger magnets, and therefore have greater field or depth of penetration. We want to be as helpful as possible and provide as much information as we can so your choice of magnetic products will be an informed one.
