Magnetic attachment system

A magnetic attachment system included in a device for magnetically attaching an accessory to the device, comprising:

• a first magnetic attachment feature at a first location in the device and comprising a first magnetic element, wherein when the first magnetic attachment feature is inactive, the first magnetic element is located at a first position, and wherein when the first magnetic attachment feature is active and providing an effective magnetic surface at a pre-determined distance and direction from the first position, the first magnetic element is located at a second position, the second position being a distance Δx from the first position in the direction of the effective magnetic surface, wherein the accessory is magnetically attached to the device in a pre-defined orientation at an engagement surface corresponding to the effective magnetic surface.

A method for providing a magnetic attachment system in an electronic device having a housing, comprising:

• providing a first magnetic attachment feature within the housing;
• and
• providing a second magnetic attachment feature within the housing separated from the first magnetic attachment feature, wherein the first and second magnetic attachment features cooperate to magnetically attach an accessory unit to the electronic device.

A magnetic attachment system, comprising:

• a dual state magnetic element arranged to provide a first magnetic surface in a first state and a second magnetic surface in a second state, wherein the first magnetic surface is unsuitable for magnetic attraction and wherein the second magnetic surface is suitable for magnetic attraction, wherein an external activator causes the dual state magnetic element to change from the first state to the second state;
• and
• a second magnetic element arranged to provide a third magnetic surface independent of the first and second magnetic surfaces.
