A magnetic seal is disclosed for releasably sealing two doors arranged side by side on a thermally insulated cabinet such as a refrigerator or freezer. A retainer gasket is affixed to the inner edge of each door. One of the retainer gaskets encloses a magnet and retains the magnet fixed in place relative to the door. Another retainer gasket is affixed to the other door and is formed of a base, a sleeve enclosing a second magnet, and two flexible webs connecting the sleeve to the base. The retainer gaskets and magnets are arranged so that the magnets impart an attractive force on each other and releasably seal the doors. When one of the doors is opened slightly, the magnets are arranged to repel each other and assist in easily opening at least one of the doors. Finally, a magnet having more than two magnetic poles may be used to assist in sealing and opening at least one of the doors.
