SUMMARY
The discussion centers on the need for a specific type of permanent magnet with a circular magnetic field, specifically a toroidal shape that exhibits either a clockwise or counter-clockwise flux. The user initially possesses a "donut" magnet that does not meet these requirements and seeks advice on how to acquire or modify one. Suggestions include sourcing ferrite cores from old computer memory or dismantling loudspeakers, which contain suitable magnets. The consensus is that a commercially available permanent magnet with the desired properties is unlikely to exist, but alternatives such as modifying existing magnets or using speaker magnets were proposed.
PREREQUISITES
- Understanding of magnetic field concepts, specifically toroidal and circular fields.
