The magnetic panel joint 118 also includes a ferromagnetic shield 153 coupled within the second pocket 150 via the adhesive 152. The shield 153 is configured to be coupled within the first pocket 150 via the magnet 149. The magnetic coupling can be beneficial by providing a selectively attachable and/or detachable interface between the shield 153 of the second panel 116 and the magnet 149 of the first panel 114. The shield 153 may be referred to as a ferromagnetic lap or a ferrous shielding plate. In examples in which the panels 114, 116 are metal, the shield 153 may provide a path to ground and may deter against radiative emission. The panels 114, 116 may have a thickness of approximately 5 millimeters. However, the panels 114, 116 may have any other thickness.

The shield 153 may include a material that is conductive (e.g., electrically coupled) to the panels 114, 116. As an example, the panels 114, 116 may include a zinc or nickel plated steel or 400-series stainless steel or another corrosion resistant ferrous backing material. Other materials may prove suitable. In another example, the shield 153 may be integral to the second panel 116. In such an example, the second panel 116 may not include the second pocket 151 and the adhesive 152.

In the example shown, an inward facing ferromagnetic shield surface 154 is substantially flush with the inward facing second panel surface 120. Additionally, in the example shown, the inward facing first panel surface 119 is substantially flush with the inward facing shield surface 154 when the ferromagnetic shield 153 is coupled within the first pocket 150 via the magnet 149.
