These pot magnets are designed to be glued in place. The glue-in magnet is magnetic on one side and flat on the other. The flat side is where you apply the glue. The glue-in pot magnets are stronger than other pot magnets of the same size. This is because the pot magnet has a larger contact area and a slightly larger magnet.
Some applications for the pot magnets are
As a locking mechanism in wood and metalwork
Organising tools on a tool board
Magnetic closures for cupboards and drawers
Hanging ceiling panels for e.g. art exhibitions
Pot magnets have a very strong magnetic pull due to their steel pot/cap. But be aware that the strength is calculated for a direct pull. If the pot magnet is placed on a vertical surface (e.g. a whiteboard), the pot magnet will hold 10-15% of the stated strength before slipping or falling off. You should therefore consider whether the pot magnet needs to hold something vertically or horizontally and choose the magnetic strength accordingly. To prevent the pot magnet from slipping, you can increase the friction by using a rubber cap or silicone washer. You can find a link to these below.
