RING-SHAPED MAGNETS.
- Most ring magnets are axially magnetised.
- North and south poles are located on the flat circular surfaces ("top and bottom").
- The few diametrically magnetised ring magnets with poles "left and right" are specifically marked.
- Rings are similar to Discs, but are hollow in the center.
- Less volume means rings are not as strong as comparable discs, however the hollow center makes them far more versatile - rings easily slide on to tubes or rods.
