Ferrite (Ceramic) Disc Magnets are round coin-shaped ceramic ferrite magnets of varying diameter and thickness. The ferrite disc magnets are almost always manufactured as axially magnetised ceramic ferrite magnets. The thickness of the magnet is how axially magnetised magnets are Our ferrite disc magnets would be supplied as axially magnetised ferrite disc magnets unless we state otherwise.

We also supply fridge magnets which may have the same dimensions as some of the discs but they work differently. The ferrite discs have been magnetised along the central axis so the poles are at either end of the disc (a North on one side; a South on the other side). Ferrite fridge magnets are magnetised such that they have multiple magnetic poles on one flat circular face and the other side is magnetically dead – ferrite fridge magnets can clamp better when in direct contact but when there is an increasing gap the standard disc magnets will start to be better at clamping – the difference is due to the pole patterns (a wider / larger pole face clamps better through gaps; narrow poles clamp worse through gaps).

Ferrite disc magnets can be stacked on top of each other to create taller magnets which can offer more potential performance (fridge magnets do not stack so productively). As the ferrite discs height increases the performance will also increase until extra height starts to give less benefit per magnet addition. Eventually the performance plateaus off as the height increases, at which point a larger diameter disc magnet may be needed if more performance is required. Starting with thinner magnets then increasing height is a good test method when you are unsure what performance and/or magnet size you require.

Ferrite disc magnets can be glued in place as required. They do not like being press fitted – too more compaction force risks breaking, chipping or shattering the magnets. The ceramic ferrite disc magnets give more pull force when attracting another magnet than when attracting a ferromagnetic (e.g. mild steel) part. Multiple Pole Ceramic Magnets
