-voltage ​source is connected to two metal rails and the circuit is completed with a metal rod perpendicular to the two rails. Two large magnets at one end of the track then generate a magnetic field causing the rod to role down the track. ​   Classes Used: Phys 102, 108 +high-amperage power source is connected to two metal rails and the circuit is completed with a metal rod perpendicular to the two rails. Two large magnets ​are set at one end of the track then generate a magnetic field which is used to start the rail gun

 +Provided with the demo:
 +  * Rail gun tracks
 +  * Steel rod
  
- +Kept elsewhere:
-  * Rail gun tracks ​second floor in the electrical room  +

-  * various metal rods : where rods are usually placed  +

   * 2 square horseshoe magnets   * 2 square horseshoe magnets
-   +  ​* [[demonstrations:​9_equipment:​power_supplies:​1000w_power_supply:​start|1000W Power Supply]] 
-  * Power supply ​(60 Amps: Green Closet at the bottom level +  * Different kinds of metal rod (optional)

-  * Place two square horseshoe magnets with the south-pole facing down in the slots provided at starting terminal of the rails. +  * Place two square horseshoe magnets with the south pole on the bottom ​in the slots provided at starting terminal of the rails. ​Place them so that the 'mouths' ​of the magnets are pointing ​down the track
-   +  * Connect the leads of the power supply to the demo, ensuring ​the left starting terminal is connected to the positive lead. 
-  * Ensure ​that the "mouths" ​of the magnets are facing ​down the length of the rails. +  * Place the rod on the rails in the opening of the horseshoe magnets. ​Make sure the rod is placed perpendicular to the tracks ((The rod should be aligned ​with the L-shaped connectors on either side of the rails.)) 
-  ​ +  * Set the power supply to the desired setting. Setting the powerstat to 60 seems to work well; higher and the arcing gets worse and the rods sticks to the track. Lower and the rod will roll slowly or not at all.
-  * Connect the leads of the 100A power supply to the demo, ensuring ​te left starting terminal is connected to the positive lead. +

-  * Place the rod on the rails in the opening of the horseshoe magnets. The rod should be alighned ​with the L-shaped connectors on either side of the rails. +

-  * Set the power supply to the desired setting ​(60 Amps is good). +

   * Turn the power supply on and watch the rod travel across the rail as it arcs and sparks.  ​   * Turn the power supply on and watch the rod travel across the rail as it arcs and sparks.  ​

 ===== Notes ===== ===== Notes =====
  
 +While the voltage across the rails is relatively low, there is a very high amperage flowing across them so burns are a potential hazard. Note that as the rod rolls it'll produce a shower of sparks; this could present a fire hazard if there'​s anything easily combustible nearby.((Things like tissues, spilled ethanol, etc.))
