Magnetic shielding in inductive power transfer

A system for magnetic shielding for an inductive power transfer, the system comprising:

• a first electronic device, comprising:
• a first connection surface;
• an inductive power transfer receiving coil positioned adjacent to the first connection surface;
• and
• a first magnetic element positioned adjacent to the first connection surface;
• and
• a second electronic device, comprising:
• a second connection surface;
• an inductive power transfer transmitting coil positioned adjacent to the second connection surface;
• and
• a second magnetic element positioned adjacent to the second connection surface;
• wherein:
• the inductive power transmitting coil inductively transmits power to the inductive power transfer receiving coil;
• and
• at least one of first magnetic element or the inductive power transfer receiving coil includes a shield that is configured to reduce an eddy current caused in the first magnetic element as a result of inductively transmitting power to the inductive power receiving coil, wherein the shield is at least partially positioned between the inductive power transfer receiving coil and the first magnetic element, and wherein a portion of the shield defines a gap between the shield and the first magnetic element.

An electronic device, comprising:

• a housing;
• an inductive coil located within the housing and operable to transmit or receive power in an inductive power transmission system;
• a magnetic field directing material positioned either within or on the housing, wherein the magnetic field directing material blocks magnetic flux of the inductive power transmission system from the housing;
• and
• a magnetic element disposed in the housing, wherein the magnetic field directing material is at least partially positioned between the inductive coil and the magnetic element, and wherein a portion of the magnetic field directing material defines a gap between the magnetic field directing material and the magnetic element.
