F12=-F21
So just as hard as a normal rifle

However this only if you accelerate the bullet at the same acceleration. If you apply a lower force for a longer time you woulde have less recoil for a long time.

>>8729047
From a practical standpoint (since we are looking at a application,) how long do you think a bullet can spend in the barrel of a gun if it's final speed is hundreds of feet/second? You can talk about lowering the force and increasing the time under force but do you really want a 20 foot gun to shoot a small projectile.

It would produce recoil equal to the momentum of the project I've fired

Hoping on the brainlet thread. I want to build a railgun for fun. What are some good ways to charge it up?

I have minimum electronics knowledge but pretty sure I want high current rails and a magnetic field 90degrees to the rails. Capacitors in series? batteries?

Should I make solenoids for the magnetic field or permanent magnets?

>What are some good ways to charge it up?

capacitors

warning: whatever you build will likely involve high voltage power, so remember to have the weapon connected to a ground in the event a short-circuit occurs

>Should I make solenoids for the magnetic field or permanent magnets?

the former since it'll weigh less and is capable of a much higher magnetic field depending on how much power is run through it

>>8729186
So a capacitor bank in parallel would be ideal with some rare earth magnets for the magnetic field

Could you hook up a DC PSU and just crank it to charge the capacitors and when you want to dump you just connect the leads to the rails?

Generally are non magnetic yet conductive projectiles used? I can see the projectile getting pulled to a side upon exiting the rails and losing velocity.
