Can a Race Car with Magnetic Wheels be Designed for a Final Project?

AI Thread Summary
A race car project utilizing magnetic wheels is being developed, inspired by a railgun concept. The design includes aluminum strips, disc magnets for wheels, straws as axles, and a matchstick box for the body. Concerns about weight and axle conductivity are noted, with suggestions to use a metallic coat hanger for better performance. The focus is on ensuring the basic functionality of the project before adding aesthetic elements, as grading will prioritize working designs over embellishments. The creator is considering a two-wheel version as a backup if the four-wheel design fails.

That is being done for my final project.

I am following this concept: http://sci-toys.com/scitoys/scitoys/electro/railgun/railgun.html

With the aluminum strips and thinking of making a race car and placing it on it.

Now, would there be any restrictions on designing a race car with 4 disc magnets as its wheels, using straws as it's axles and maybe a match stick box as the body? would weight be an issue to carry the car along the aluminum strip when the alligator clip leads are connected? or am I good to go?
 
Physics news on Phys.org
I think the axle needs to be metal for conductivity between the two aluminum foil strips but you could wrap the axle with the plastic straw and build your car body on it.
 
yeah, i am following the exact break down given in the link. using a metallic coat hanger, and using that as the axles. i am just using the straws so that it can rotate in a match box, as a car and to kind of make it a little aesthetic and not as if i didn't put much effort into the design. i am assuming this will work. but this is my first time taking a physics course and i am not much of a physics person. =/

First get it to work as described in the article and then later try adding your extras to it.

The teacher will grade on your basic project working not on the frills but may give you some points for elegance only if its working.

Will definitely do that. Was thinking of making two wheel cars lol, just in case when i tweak it, it doesn't work with the 4 wheels.

Thanks again for your responses.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
