m impact to prevent it from breaking while increasing its overall magnetic strength. A layer of rubber is applied to the entire surface of the magnet.
Rubber-coated magnets have several advantages:
- They are waterproof and can therefore be used outdoors.
- They have high friction. Therefore, they don't easily slide off the surface.
- They will not scratch the surface on which they are placed.
The disadvantage of rubber-coated magnets is that a layer of rubber creates a gap between the magnet and the metal surface, which reduces the
magnet's attractive force. They are therefore slightly weaker than conventional
pot magnets of the same dimensions. However, you can achieve the same strength by using a larger magnet.
The magnets have a thread on one side that you may or may not use.
