Analysis of Railgun vs Coil gun technologies - Physics Book
2016年11月27日 · The main difference between a rail gun and a coil gun is how each gun propels its projectile. The rail gun uses Lorentz Force by passing a current through two metal rails and the projectile, causing a magnetic field to be produced that interacts with an external field, and thereby produces force via F = ILB equation.
Coilgun - Wikipedia
The coils are switched on and off in a precisely timed sequence, causing the projectile to be accelerated quickly along the barrel via magnetic forces. Coilguns are distinct from railguns , as the direction of acceleration in a railgun is at right angles to the central axis of the current loop formed by the conducting rails.
A railgun usually has magnetic coils mounted on either side of the rail system at right angles to the barrel, so as to generate Lorentz Force. There are several potential variations of the railgun that successfully meet
The Physics of the Railgun - WIRED
2014年8月12日 · A coilgun uses a series of electromagnetic coils to accelerate a ferromagnetic projectile. For the railgun, the projectile is accelerated because of a current running through the projectile.
Railgun - Wikipedia
Some railguns also use strong neodymium magnets with the field perpendicular to the current flow to increase the force on the projectile. The armature may be an integral part of the projectile, but it may also be configured to accelerate a separate, electrically isolated or non-conducting projectile.

2008年6月9日 · Launchers of interest include the dc railgun driven by energy stored inertially in a homopolar generator and transferred through a switching inductor, and the opposite extreme, the synchronous mass driver energized by a high voltage alternator through an oscillating coil-capacitor circuit.
How Rail Guns Work - HowStuffWorks
One solution is the electromagnetic rail gun, or rail gun for short. Using a magnetic field powered by electricity, a rail gun can accelerate a projectile up to 52,493 feet (16,000 meters) per second. And while current Navy guns have a maximum range of 12 miles, rail guns can hit a target 250 miles away in six minutes.
Railgun Physics - MIT
The underlying physics involved in the railgun are rather simple. Current flowing through an inductor creates a magnetic field. The current flowing through the field creates a Lorentz force on the inductor tending to push the coil apart. If one portion of the coil is free to move, this portion will slide away from the power source.
A coil-gun, like a rail-gun, uses magnetism to propel a projectile. The purpose of this honors project was to create a system that mirrored the effects of a coil-gun without actually creating a dangerous weapon. While this technology was patented back in 1900, its progression has been surprisingly minimal. Building a Basic Coil-Gun:
What is the theory behind a railgun? - Physics Network
2023年5月12日 · How does a railgun work physics? A coilgun uses a series of electromagnetic coils to accelerate a ferromagnetic projectile. For the railgun, the projectile is accelerated because of a current running through the projectile. This means that it only needs to be an electric conductor and not a ferromagnetic material. Why is it called a railgun?
