I'm not sure I understand how you can draw a comparison between LN2 and small magnets.
An adult could quite easily harm themselves or others when playing with LN2, in a lot of ways that aren't inherently intuitive, or just because they are a bit lax with precautions.
An adult is very unlikely to just swallow a magnet for no reason, much less multiple.
> The CPSC appeared to have been fine with that too; its problem wasn't with you owning little magnets
This isn't true. https://www.cpsc.gov/Regulations-Laws--Standards/Rulemaking/Final-and-Proposed-Rules/Magnets https://www.cpsc.gov/Regulations-Laws--Standards/Rulemaking/...
"objects that are marketed or commonly used as a manipulative or construction item for entertainment, such as puzzle working, sculpture building, mental stimulation, or stress relief."
Even if they were not marketed as such in any way, any magnet set that was commonly used for this would have to have flux index of 50 kG2 mm2 or less.
The CPSC's ruling basically banned the sale of spherical strong magnets to consumers.
- TheSpiceIsLife 8y agoI'm not expert in the field, but what purpose does the average person have for small spherical strong magnets? I know a few people of various professions, trades, students, and I've never known anyone to have a use for spherical strong magnets that wasn't manipulative or construction item for entertainment.
- kevinmchugh 8y agolarger than zen magnets, they're useful in repairing dings and dents in brass instruments
- TheSpiceIsLife 8y agoI suspect you’re not using spherical magnets for this purpose?
- akerl_ 8y agoIs there a list of shapes you consider worthy of retail sale? You seem to have posited that no use case could exist, and as each person mentions a use, you respond to ask ~"but really?"
- cthalupa 8y agoI use magnets that are stronger in gaming figures. I have a board game that came with a bunch of "Armor Kits" for the plastic figures. If I just used plastic cement to assemble them, they would no longer be customizable. Instead I drill out small holes for magnets on the various pieces, superglue them in there, and then I can swap our pieces as needed. I suppose the end goal is still entertainment, but they are a utility piece in this example, and you could use them similarly for anything you are building where you want a small magnet.

- cthalupa 8y agoMostly, no. But they work well if you want to emulate an articulating joint
- tptacek 8y agoI'm sorry, but I don't understand what you're saying. CPSC's Final Rule specifically says the action pertains only to magnets marketed as entertainment devices.
- cthalupa 8y agoMarketed or commonly used That specifically is an or statement, not and.
- tptacek 8y agoThey're commonly used that way because of how they're marketed. The idea is that it's probably fine if you're acquiring these in lots on Alibaba the way you would a bundle of sapphire crystal rods or whatever, but it is not OK to sell them on a site that has a streamlined checkout flow and exists to promote the magnets as entertainment. In other words: it'd be OK if they were sold if you specifically had to know what you were looking for to get them, just like with LN. (Obviously this is all a moot point now.)
