General Atomics Makes a Very, Very Large Gun



Above is how a basic info graphic explaining how a railgun works.  Below is the General Atomic’s new Blitzer Railgun’s test apparatus.


From the PopSci article: “railguns mount the projectile on two magnetized rails (hence the name), which then propel the shell out of the muzzle using electrical conductivity.”

This stuff really fires me up.  It was Faraday’s Law of Induction, Lenz’s Law, and the rest of Maxwell’s equations that made me love physics, ultimately driving me towards electrical engineering.

Check out this video demonstration from the Discovery Channel about a Navy railgun prototype:
