[* black] The Touchstone rear panel includes a secondary induction coil. | |
+ | [* icon_note] The magnetic field generated by the base unit turns on and off rapidly, generating a magnetic pulse that is carefully tuned to the dimensions of the wire coil inside the phone. This oscillating magnetic field induces a current inside the phone, allowing the battery to be charged. |
+ | [* icon_note] Similar technology is used to transmit power to some battery-operated toothbrushes, razors, etc. |
+ | [* black] This explanation is an oversimplification of a [link|http://en.wikipedia.org/wiki/Wireless_energy_transfer#Near_field|very specific field] of electrical engineering. |
[* black] You'll note that the location of the induction coil is in the center of the device, well away from the antennas that line the perimeter of the phone. |
