Ener-Flex™ Magnetic Shoe Inserts

The Manufacturer's Gauss Rating is an industry standard measurement that tells us the maximum amount of magnetic energy that a particular type and grade of magnet can hold.

This measurement remains constant, regardless of the number of magnets a product contains.

In other words, if a magnetic therapy product contains 10 magnets, and each magnet is rated at 4,000 gauss, the Gauss Rating of the product is still 4,000 gauss. It does not increase.

You may have noticed the term Penetration Depth on some websites used as a way of relating product effectiveness. This is the distance from the magnet where the strength of the magnetic field is no longer measureable.

The above method is meaningless in magnetic therapy because the magnetic field loses all therapeutic effectiveness long before that point.

At Therion, we developed the term Effective Penetration Depth. This is the distance from the magnet where the strength of the magnetic field is no longer therapeutically effective, which is significantly less than the Penetration Depth.

Using a 3,950 gauss, 4" x 6" x ½" ceramic magnet as an example:

The Penetration Depth is 22".

The Effective Penetration Depth is only 16".

The magnetic field is ineffective past 16".
