Rail Gun Magnetic Drive Possibility

By | April 13, 2016

Some time ago, I saw a YouTube video where a couple of kids and made a magnetic gun from angled ceramic magnets. That darn thing shot the magnet projectile out like a rocket. I thought that if this principle could be used in a more rounded situation, there was some promise.


I did some calculations and made a scale drawing of the concept just as I plan to do with every experiment from now on. My original motor design was lost over the past few years, and even though I have photos, I don’t believe I can duplicate it exactly. I don’t plan to let that happen to me again.motor4-1

The mechanism is driven at the base by a series of (10) angled 1 7/8″ x 7/8″ x 3/8″ thick ceramic magnets, mounted on a platform at 45º, creating a trough through which a series of 1 7/8″ x 7/8″ x 3/8″ magnets (4) mounted to a wheel, along with (12) 3/4″ X 1/2″ X 1/8″ thick quadrilaterally spaced flat magnets will pass through. This wheel and magnet on the wheel configuration is the exact same one I used in the video posted at http://maginvent.com/2016/04/11/starting-again/, or at least as close as I could get it.


The (12) 3/4″ X 1/2″ X 1/8″ thick quadrilaterally spaced flat magnets are for magnetic balance only, but I hope they may add to the pull from the gate if the magnetic flux is aligned properly.

    You might want to place your drive magnets in a slight arc also. I’d like to see a video of the motor once you got it built.

      Well Monty, I think I’d like to try the flat version first. If it produces too much drag, then I’ll move to the arced version. Just the process of elimination to start with.

    I firmly believe in the reality of a magnet motor. If them kids can make a projectile move so far on magnets why can’t you have the projectile go in loop an keep going through the magnets for its boost to keep rotation going. I might want to give this a try myself. Goodluc, post yours when your done.

      Thanks Jeremiah. That’s encouraging. Let me know how things go with it. I probably won’t build mine until I take care of a few heart health problems. Maybe in the next month or so.
