Your Apple iMac may soon be wirelessly charging iPods, iPhones and iPads

” Is based on the mid range wireless power transfer physics described in this paper (.pdf). It makes use of wireless near field magnetic resonance (NFMR) power transmission to power devices up to 1 meter distant.

Apple’s NFMR power supply will be integrated into desktop iMac or Macbook Pro and will create a 1 m zone in front of it, where computer peripherals like mouse and keyboard, or smaller devices like iPods, iPhones and iPads can be wirelessly charged. Peripherals, of course, will have to be equipped with special coupling antennas able to received the power.
To expand the wireless charging zone, the antennas in peripherals can be configured to act both as power receivers, and repeaters – sending some of the received power down the line and expanding the charging zone coverage.
And, just to make sure that your older Macs can wirelessly charge everything else, Apple proposes to also build NFMR power supply into separate USB dongle.
