Q: How do rod magnets compare to disc magnets of the same diameter?
Rod magnets are more powerful than disc magnets of the same diameter because the greater length provides more neodymium volume and a correspondingly higher magnetic force.
Rare-Earth Rod Magnets
This item is not available for this region.
Until you have actually used rare-earth magnets, you cannot appreciate their strength. The strength of these magnets has to do with the electron array in the neodymium, the rare earth they are made from. This force only increases with the magnet’s dimensional size.
These rod magnets are more powerful cousins of the 0.25" circular magnets. By combining them with the 1/4" inside diameter ring magnets, you can create interesting mechanisms of all kinds.
Nickel plated with slightly rounded edges, they can be glued in place with almost any glue (epoxy is the most secure).
Dimensions given are diameter by length. The 1/8" × 1/8" magnets are sold only in packs of 10; all others are sold individually.

Yes, rod magnets can be combined with 1/4" inside-diameter ring magnets. Stacking ring magnets on a rod with like poles facing creates repulsion-based floating mechanisms and other multi-component magnetic assemblies.
Most sizes are available individually. The 1/8" × 1/8" magnets are available in packs of 10 only, given their small size and handling requirements.
