I wonder if anyone can help with my magnet launcher experiments? I've obtained 56 1000uF 450V caps which I plan to wire in parallel to make one 56,000uF 450v which I will discharge into a coil (by smacking two copper plates together with a hammer) .I guess I need to design the coil so that the resistance and inductance is such as to cause a critically damped response? How do I do this , first ignoring the effect on inductance caused by the projectile, then what effect would an iron or neodymium magnet entering the coil have on the calculations. Is it OK to take the caps a little over their rated value, just for a few seconds? Thanks in advance for your help...
