Product Description A pot magnet is a permanent magnet encased in a steel shell, which is sometimes called a pot, hence the name 'pot' magnet. A permanent magnet emits a magnetic field without the need for any electricityThe steel shell helps the pot magnet by increasing its holding power and providing the magnet with added strength and stability.  Pot magnet spacerA spacer acts as a barrier in-between the magnet and the steel shell to avoid any demagnetizing effects the steel may have on the magnet. A spacer in a pot magnet can either be made of brass or plastic. Rubber cap and rubber coating on a pot magnetPot magnets can have a rubber coating on top of their steel shell which allows them to be used on surfaces where the user does not want the magnet to scratch, such as on a car roof.  If the pot magnet does not have a rubber coating, there is the option to buy a rubber cap which is easy to press onto the magnet and to remove. The rubber provides the pot magnet with friction which allows the magnet to be clamped on vertical surfaces so they will not easily slide off. However, the rubber cap or rubber coating on a pot magnet creates an air gap meaning the holding capabilities of the magnet can be reduced.
