Electronic connectors with magnetic copper alloys

A method for making an electrical connector, comprising:

• placing a copper alloy on a body, the copper alloy comprising nickel, tin, manganese, and balance copper;
• and
• heat treating the copper alloy to convert the copper alloy into a magnetic copper alloy.

An electronic device comprising a connector, wherein the connector includes at least one magnetic portion formed from a copper alloy comprising nickel, tin, manganese, and balance copper.

A method of mating a host electronic device with an accessory comprising:

• inserting a plug connector of the accessory into a receptacle connector of the host electronic device, wherein the receptacle connector and the plug connector each include a magnetic portion that attract each other, such that the withdrawal force is increased;
• wherein at least one of the magnetic portions is made from a copper alloy comprising nickel, tin, manganese, and balance copper.

A system comprising:

• an accessory with a plug connector, wherein the connector includes at least one magnetic portion, wherein the at least one magnetic portion is made from a copper alloy comprising nickel, tin, manganese, and balance copper;
• and
• a host electronic device with a receptacle connector, the receptacle connector including a magnetic sensor adapted to sense the magnetic portion of the accessory.
