What are you using for magnets?
What are you using for an axle?
What are you using for a power supply?
Check that you are getting a current flowing in the device.
You can do this by putting a meter or a light bulb in series with
If you have current, check that you have enough.
The railgun uses batteries quickly, because it uses a lot of current.
You should see sparks when the magnets first touch the rails.
If the axle twists around instead of running along the rails,
then reverse one of the magnets.
The magnets must conduct electricity.
The battery should be fresh, or large, or both.
12 volts is better than 9 volts.
1.5 volts probably won't work.
