>Be me>2nd year EE student>Doesn't how coil guns workSomeone explain it to me before I anhero myself
>>10196057Do you know how a solenoid works
>>10196057A charge is stored in a capacitor bank. Some high power switch dumps all the power from the capacitors into the electromagnetic coil pulling the metal projectile towards the center of the coil. In a well tuned coilgun, by the time the projectile reaches the center of the coil it has run out of energy so the projectile keeps moving forwards using momentum.The picture you used shows a multistage coilgun which basically uses some sort of switching mechanism to do the same thing again when the projectile is in the right spot.
>>10196058Yes - a current in a solenoid creates a magnetic field due to amperes law - I just don't know why the bullet is pulled to the center of the coil
>>10196064Right but why does the bullet go towards the center of the coil
>>10196065A magnetic field in the direction of the chamber, which propels the projectile through the chamber. Right hand rule a solenoid coil and the direction your thumb is pointing is the magnetic field. If you're asking why a magnetic field has an effect on the projectile itself well I can't answer that, something something fundamental properties of magnets
>>10196068I think the basic explanation is that the magnetic field induces current to flow through the projectile because of mutual inductance. That current flow turns the projectile into another magnet which is attracted towards the field of the electromagnet. It goes to the center, because that is where the field is the strongest.
>>10196069Hogwash - There has to be an explanation aside from>Magnets do be that way sometimes
>>10196070Ok that makes more sense so then the current would be flowing in the bullet cylindrically?
you really want your mind blown look up how a railgun works
>>10196074I think so. That is sort of my half ass explanation.I found some websites that might be helpful.http://www.doityourselfgadgets.com/p/coilgun-knowledgebase.htmlhttps://electronics.stackexchange.com/questions/8745/how-does-a-coilgun-workYou probably have more 'official' electrical qualifications then I do. I was just super into this stuff when I was a kid.
