Abstract
A first electronic device connects with an second electronic device. The first electronic device may include a first connection surface and an inductive power transfer receiving coil and a first magnetic element positioned adjacent to the first connection surface. The second electronic device may similarly include a second connection surface and an inductive power transfer transmitting coil and second magnetic element positioned adjacent to the second connection surface. In the aligned position, alignment between the electronic devices may be maintained by magnetic elements and the inductive power coils may be configured to exchange power. The magnetic elements and/or the inductive power coils may include a shield that is configured to minimize or reduce eddy currents caused in the magnetic elements by the inductive power coils.
