i want to make a coil gun but i don't understand why there is a need of a camera?
A coil gun works by charging a capacitor up to a high voltage, then discharging the stored energy through a coil, creating a strong magnetic field that accelerates the projectile towards it.Any charging circuit and capacitor bank large enough will work, but the one used to drive the flash in a camera is cheap and easily available, so is widely used.

can i use a simple capacitor?
Any capacitor or bank of capacitors that stores enough energy will work. You still need a suitable DC source to charge the capacitor though.
+1 The camera is the cheapest way to get the charge circuit and capacitor to make a very basic coil gun.
