FIG. 3 illustrates a detailed expanded isometric view of another example of a magnetic panel joint 118 of the system 100 of FIG. 1 including the first panel 114, the second panel 116, and the shield 153. The first panel 114 includes an end portion 155 defining the pocket 150 and a plurality of the receptacles 156. The pocket 150 terminates at an end face 157 of the first panel 114. In the example shown, the pocket 150 is defined along a majority of the height H of the first panel 114. The pocket 150 may have alternative dimensions.

The receptacles 156 are positioned in a staggered arrangement. Alternative arrangements for the receptacles 156 may prove suitable (see, for example, FIG. 8). While seven receptacles 156 are included in the example shown, a different number of receptacles 156 may be included including one (see, for example, FIG. 9).

The pocket 150 includes an end opening 158 and is contiguous with the receptacles 156. The end opening 158 is defined by the end face 157 of the first panel 114. A lateral opening 159 of the pocket 150 is defined by an inner first panel surface 160 of the first panel 114. The pocket 150 has a rectangular cross-section and has rounded-back corners 162. The rounded back-corners 162 may facilitate manufacturability using, for example, a milling machine.
