Railgun - Wikipedia
Schematic diagram of a railgun. The railgun in its simplest form differs from a traditional electric motor [5] in that no use is made of additional field windings (or permanent magnets).
How Rail Guns Work - HowStuffWorks
In a rail gun, the two rails act like wires, with a magnetic field circulating around each rail. The force lines of the magnetic field run in a counterclockwise circle around the positive rail and in a clockwise circle around the negative rail.
The Physics of the Railgun - WIRED
2014年8月12日 · You have two parallel rails (thus called a railgun) and a moveable projectile that is also like a wire. An electric current goes down one wire, across the projectile and then back down the other...

2015年12月5日 · Schematic diagram of a railgun. A Mathematical Model. The Lorentz Force is the primary component in creating a railgun and is best know by the formula below: F = I ∫ d ℓ × B.
Table-top demonstration railgun - MIT
A railgun consists of two rails with a projectile in between. A current is passed down one rail, through the projectile, and back through the other rail. A magnetic field is set up around the currents in the rails, in the same way that a magnetic field is set up around any wire carrying a …
Physics 210 Railgun Project - Princeton University
Objective: construct and fire a rail gun. Definition: a linear electromagnetic accelerator consisting of two rails and an armature in which the large amounts of current are passed through the rails to accelerate the armature by a Lorenz force. Below is a schematic view of the rail gun from the top. (We created this awesome image ourselves!
The figure below, from Poynting [96], illustrates lines of S flowing from a battery to points along a circular resistor. We find below that for the examples of railguns with no “battery”, nonzero work is done on the crosspieces.
Rail Gun | UCSC Physics Demonstration Room
Figure 8: Rail gun diagram, from Hacksmith. Current travels from the power supply, down one rail, through the projectile, and back through the other rail to the return of the power supply. The direction of magnetic field produced by this current follows right hand rule with magnitude, .
How Does a Rail Gun Work? - Saint Mary's University
The rail gun uses electromagnetic induction to launch a metal ring into the air. Watch Video: Teachable Topics: Magnetic fields. Induced current. Circuits. Theory: In this demo, an aluminum ring is placed on a post that can create a magnetic field at the flip of a switch.
The Rail Gun ( Real World ) | Physics - CK-12 Foundation
2014年1月10日 · This rail gun fired a world-record setting 33 mega-joule shot. A rail gun consists of two parallel guide rails that are connected to a power supply. When a conductive projectile is placed on the rails, a magnetic field is created that is perpendicular to the rails.
