A few tons of superconductors work very well against bullets.
- Terr_ 3y agoThat's true even without power at room temperature. :P
- willis936 3y agoWho's making a 600 T magnet that weighs only a few tons? https://physics.stackexchange.com/questions/115011/how-much-power-would-it-take-to-stop-a-bullet-with-a-magnet#115014 https://physics.stackexchange.com/questions/115011/how-much-...
- hobofan 3y agoI think at that point you probably have to worry about the effect such a strong magnet will have on the brain and nervous system, so probably not the best fit for personal protection.
- skhr0680 3y agoI’m no rocket scientist, but I feel that statement holds true for bullets too
- bee_rider 3y agoThe bullets are the problem they are trying to use the shield to solve. If the shield also kills the user, that sort of renders the whole thing moot, right? Not to agree with the actual idea that the magnet is necessarily dangerous, haven’t looked that up…
- Arrath 3y ago> If the shield also kills the user, that sort of renders the whole thing moot, right? Depends, are you the mook hiding behind the shield, or the contractor making and selling a million shield units?

- idunnoman1222 3y agoI think you actually have to worry about your soldier not having any metal objects on him because I don’t know what use he’s going to be naked
- Scarblac 3y agoYou don't need 600 T, just a few tons of superconductor should be enough to stop most bullets. No need run any charge through them, just place them so that most of it is between you and the bullet.
- theultdev 3y ago> just place them so that most of it is between you and the bullet. Easier said than done
- willis936 3y agolol this is true. The 6 order of magnitude resonant eddy current induction looks like the more interesting solution. I could see this being done with a giant beamforming array that would be more practical than a giant steady state magnet. It would be pretty cool to melt a supersonic projectile midflight with eddy currents.
- bee_rider 3y agoIn sci-fi, shields seem to basically evaporate bullets. A shield that melts bullets could be a very cool sci-fi visual; the ship would still need some conventional armor (you still have molten metal flying at you), but it would splat against the armor. Plus it would provide a nice visual for a fresh fleet vs the battle-splattered one that’s seen combat.

- mr_toad 3y agoFrom small arms. A heavy machine gun can cut through an engine block and still kill you.
- tzs 3y agoThat’s for stopping the bullet. All I need from a personal bullet shield is to deflect it enough to miss me.
- perlgeek 3y agonot against silver bullets :-)
- theultdev 3y agoor more practically, titanium bullets. the lead in them may be a problem though.
- myrmidon 3y agoA strong magnetic field would affect all (eletrically conducting) bullets, they need not be ferromagnetic. This would work better on silver bullets than steel, actually (because of better conductivity). (This is obviously not practical)
- f4c39012 3y agofortunately software engineers know there is no silver bullet
- scotty79 3y agoNot really. Bullet would just orient itself to minimize eddy currents. People would start using thin disc shape bullets that would slide through the magnetic field without much trouble after orienting themselves in the best direction. https://youtu.be/g0amdIcZt5I?t=735 https://youtu.be/g0amdIcZt5I?t=735
- willcipriano 3y ago> thin disc shape bullets Very powerful fans blowing in the direction of the flat side
- scotty79 3y agoRings then.
- Leo_Germond 3y ago"Just fire discs" well that's easier said than done, and there's probably a tons of reasons nobody uses discs. One of them is already that we have no experience building or using disc-shaped bullets, especially compared to the trove of experience for... bullet-shaped bullets. So that's not a solution as much as it's an indication that this defense mechanism wouldn't be perfect given an adversary with enough time and will. That being said, nothing is ever perfect, and "arms race" are named this way for this exact reason.
- wkat4242 3y agoA few tons of steel is cheaper and also works very well against bullets
- roamerz 3y agoProbably would be more efficient to vaporize a bullet with a directed energy weapon than to stop it with a magnet.
