]Actually, the thing with magnetic "Therapy" is just a myth. There are a lot of products that claim they do something, but the magnetic of them have absolutely no effect in what they are claiming. There are some devices that use magnets and do serve a purpose. But it's not the magnetism that plays a part in their function. The only thing the magnets do in such devices is apply the pressure and the right "pressure point" Some on ear, some on nose, etc...). But it doesn't have to be a magnet to apply that pressure. That's just a convenient way to do it in the engineering of them. For example rather then having some kind of device that uses a clip to apply pressure, two magnets can apply that pressure (Such as magnetic ear rings opposed to clip on).
But when it comes to our CI. Think about what options there are to hold it in place. Some kind of strap could work, but they don't always stay still (Such as a head band or hat moving up, down and side to side). Velcro? Who'd want that on their head?
Some kind of snap sticking out of your flesh? I couldn't want that. So a magnet is a good way to hold it in place. It's not going to move, It doesn't matter if you have hair or not. You can adjust how strong the magnet/hold is to some degree.
So yea, it's only purpose is to hold it there.
