Use a compass to indicate North and South poles. If you are not handy or simply don't have time to build the foot braces, you can buy the foot braces from us. We only build my devices with the best quality magnets possible. Watch out for the polarities of the magnets. If you have the wrong polarities, you can get sick within hours.
Nonconductive brace creates little energy loss for the magnetic device.
You can use ceramic or rare earth magnets. You can find ceramic magnets in every hardware store. Since it is an eternal life device, it's better to purchase good quality, powerful magnets for the sake of your great health . Rare earth is a little more expensive, but they are much more powerful than ceramic. I recommend rare earth magnets.
