Diameter (Inner/Outer) 31mm+
There is a magnitude of products in our range. Our magnets are organised based on the type of magnet or product. However our range is so comprehensive the sheer number of products can be a little daunting. To assist our customers to find the best products for their needs we have also created helpful categories that group together products based on size, strength and coating. This category features a veritable feast of magnets, all with a diameter of more than 31mm.
The magnets in this category all have one thing in common, this is that their diameter is greater than 31mm. At this size, magnets are reaching into the more powerful end of the scale. These magnets are certainly not considered small magnets and they can achieve substantial pull forces. There are a number of ring magnets, cylinder magnets and disc magnets available in this category. However the larger diameter magnets included here are predominantly pot magnets.
Pot magnets
Pot magnets are extremely diverse, with many different shapes, styles and forms available. Pot magnets are not a shape per se, but rather a magnetic product. Most pot magnets are a round steel cup with a disc or ring magnet seated inside. The steel cup features an attachment point such as a threaded hole, eyelet or countersunk hole among other options.The steel cup of the pot magnet provides two key benefits. Magnets, particularly Neodymium magnets, are brittle and are prone to chipping and breaking. The steel case provides protection against impacts on the magnet either while handling or in use. Secondly the steel case enhances the magnetic power of the magnet. When the magnetic field of the internal magnet encounters the steel case it is deflected and pushed towards the working face of the magnet. This makes one side of the magnet far more powerful and reduces the stray field produced out the rear of the magnet.
Not all pot magnets have a round steel cup construction as described above and there are a number of exceptions to this description. Firstly rubber pot magnets which consist of a rubber disc with a number of small disc magnets embedded in the rubber. These magnets are arranged in a circular pattern around the central attachment point of the pot magnet. Another anomaly are rectangular pot magnets, these feature a steel U profile bar within which the rectangular magnet sits. These have countersunk holes and the screws used to secure the magnet also serve to hole these two elements together.
