simple rail gun (linear DC motor) experiment

a simple demonstration of the force developed on a current-carrying wire within a magnetic field.

This idea for this experiment came from the book Electric Machinery Fundamentals, by Stephen J. Chapman, fourth edition (4th ed) - section 1.8, page 36.

do you realy need the magnet?

@seth14born95

yes! see the equation at the end of the video? "B" is the strength of magnetic field. If there's no magnet, B=0, and then Force = 0 on the aluminum rod.

Awesome! Instead of rambling on about useless information, you got straight to the point. You showed us how it works, and what happens if you don't use a resistor. :)

There's no reason why you shouldn't get a 5/5 rating on this video.. except the fact that you can only "like" videos now -.- Otherwise, nice job!

Thanks for the comment, and I'm glad you enjoyed it.

Good shit.

Which is the source voltage??

[spidey1242]

so you made an mhd motor.
