# How can a small pocket device give full body coverage?

#1 - ​It's resonating with the water in your body like a pebble in a pond​. ​So the energy enters the body where the device is located​, but it travels just like a wave on water​. Again think of it like a pebble in a pond​. One reason we believe this is happening is it doesn't work as well if you are not hydrated - which is a good clue.

​#2 - The other is that an alternating magnetic field will create an electrical current​, albeit at a very small one​. ​That electrical current is traveling through the body because the body's electrically conductive​.

​So it's those two principles ​that allow ​the energy to travel further than just the magnetic field ​itself.
