coilgun recoil/kickback demonstration

I made this video to demonstrate that coilguns DO HAVE RECOIL...even the small ones' kickback can be noticed.I saw plenty of people(including the one commenting your video) that completely lack physics knowledge and are convinced that you can launch a projectile with having no reaction at all.

could it have something to do with the weight of the projectile? like it was too heavy so the coil launched itself?

@DeathBringer9000 yea that's pretty much what happens.the projectile's inertia tends to keep it in place while the magnetic field propels it. An equal reaction is exerted on the gun. This would apply to ANY kinetic ranged weapon, so any gun, coilgun, railgun, crossbow, slingshot or whatever will always have some amount of recoil.

ya i made one and it does but what did u use to charge that wow i really need one of those where did u get it?

[mrkiky]

@njkl44 it's like all of those mini coilguns, a camera flash circuit.

[njkl44]

i no well it looks way different cuz i built one and ya idk it looks like u bought that

[mrkiky]

well yea of course I bought it, it's a camera flash :| I didn't make my own pcb and solder all the components, I had no idea how.

[Dazzerlikestech1]

how do you make one of these, send a email to me in my youtube inbox

[njkl44]

well was it a disposible camera cuz i never saw anything like that just a board from a camera is what i used but wow thats prett good its a good setup

[ha1e]

it dosnt )

it does
