Contents of part 1• What are rail guns?• How can I propel a projectile using ONLY electrical current?• How far does the projectile travel?• How much impact is possible with such a weapon?• What should I do if I want to make one myself?

WHAT IS A RAIL GUN?A rail gun is entirely electrical weapon which fires a conductive projectile along a pair of identical metal rails.Rail guns use rolling or sliding contact.High current is made to pass through the rails and the projectile.The electromagnetic force produced is so strong that the projectile is driven right through the two rails.

HOW TO PROPEL A PROJECTILE USING ONLY ELECTRIC CURRENT?!

As seen earlier, the rail gun has two rails parallel to each other. The projectile is conductive and it is in contact with the two rails all the time until it leaves the end of the rails. Extremely high current flows through the projectile creating an enormous amount of force. This force drives the projectile out towards the trajectory.

HOW MUCH FORCE?The force generated by the rail gun is so high that you can see plasma explosion behind it!The explosion is caused because of intense electric current, friction between the rails and the projectile.

LETS DO SOME CALCULATIONS

AVERAGE MAGNETIC FIELD ALONG THE LENGTH OF THE RAILS
