Can I wear my magnetic bracelet whilst using my computer or tablet?
Magnetic bracelets placed directly over the surface of a laptop may have an effect of the hard drive. There will be no effect when working with desktop PC, as it is away from the wrist. Also, there is no wrist operating a mobile phone for the same reason.
There is a simple solution for the issue of working on a laptop while wearing a magnetic bracelet: Keep the bracelet about one inch away from the edge of the laptop. That will be enough. The same rule apply to all other electronic devices such as headphones and speakers.
The reason is that electronic devices are effected by magnets is that magnets discharge positive and negative magnetic charge. The magnetic field, when gets near an electronic device, effect the electrons inside the device, and changes or destroy the content embedded in them. However, the magnetic field of the magnets used in all magnetic bracelets is just about strong enough to effect at a distance of less than an inch, as it meant to be worn near the skin.
