levitating train project
 
I am doing a project on a maglev train, but am having trouble deciding what to test! I have to use the scientific method..hypothesis etc...
What can I test a levitating train for?
It's already built and ready to go.

Hi Marc.

Very interesting project.

In these days energy and productivity (get more with less) is very important for the industry and for the economy.

You can test or demonstrate that this trains is more efficient and environmental friendly that gas/fuel or electric trains.

Or, you can build an Hypothesis by observing at which height the magnetic field loses power and the train comes unstable….?

Hope that this inspires you to come up with an idea.

Best regards

Oscar

levitating train project
 
thanks oscar...i do need to come up with my hypothesis first..
so your idea on height is a good one. what would the hypothesis? How does height affect the strength of the magnet?
i could measure the height or angle and test it a few times to see if it looses strength?
do you think i could test how weight would affect the speed of the "train"
i just don't know how..i guess i could time how fast it went without any weight and then test it and keep adding weights to it and see if it speeds up or slows down.
what do you think?

Sorry I could not reply to your post promptly
I work everyday from 8 to 6 an sometimes I have to stay late at work. All apologies.

I think that a good hypothesis will be your idea on adding weight to the train instead of measuring height.

If you add weight to your train it will slow down, that is a fact. But how about if you build your hypothesis by stating that if you use a specific material in the frame of the train that will help it to gain speed.
For example, big trucks switch from steel to aluminum in the wheels because aluminum alloys are strong enough to do the task and also they are a lightweight material.
They gain speed and work efficiently because they save fuel…also.
So, how about if you try different materials, run your experiment and come up with some result. Build a chart to show your results and select a material as a winner after proving your hypothesis.

Hope this works for you.

Best regards

Oscar
