The second shield portion 184 is disposed within the first pocket 150 of the first panel 114 via the end opening 158 to form the magnetic lap joint 118 (block 1010). The inward facing shield surface 154 and the inward facing second panel surface 120 are substantially flush with the inner first panel surface 160 of the first panel 114.

A method, comprising: forming a pocket and a receptacle in an end portion of a first panel, the pocket having an end opening and being contiguous with the receptacle; coupling a magnet within the receptacle; forming a pocket within a second panel that terminates at an end face of the second panel; coupling a first shield portion of a ferromagnetic shield in the pocket of the second panel such that a second shield portion of the ferromagnetic shield extends from the end face of the second panel, an inner shield surface of the ferromagnetic shield being substantially flush with an inner second panel surface of the second panel; and disposing the second shield portion of the ferromagnetic shield within the pocket of the first panel via the end opening to form a magnetic lap joint, wherein the inner shield surface and the inner second panel surface are substantially flush with an inner first panel surface of the first panel.

The method of any one or more of the preceding examples and/or any one or more of the examples disclosed below, wherein forming the receptacle comprises forming a plurality of receptacles in the end portion of the first panel and wherein coupling the magnet within the receptacle comprises coupling a magnet in each of the plurality of receptacles.
