what kind of switich could i use to turn on the power from the capaciter and how do i find the curent coming out of the capiciter
thanks for the help
 
Coil gun

A SPDT switch would be suitable. The initial current will depend upon the initial capacitor voltage, the resistance and the inductance. If the L is relatively small, then I = V/R (approx) where V is the capacitor voltage at t = 0 and R is the total series resistance.

If L is significant, then it is more complicated. A circuit simulation program would do it for you if you can't do the maths. If that is not an option, send me a PM and I'll do the maths for you.
