How to write the question for eddy current project?

Postby tigerlily6200 » Sat Sep 09, 2017 6:26 pm

My 5th-grade daughter would like to do one of the eddy current projects listed on this website.

Abracadabra! Levitating with Eddy Currents!
https://www.sciencebuddies.org/science- ... y-currents

She is fascinated by the concept and has been reading up on the subject. What she is having a problem with is expanding on the question for the experiment. The original question is which material does the magnet pass through the fastest and why? She wants to expand on that and I was wondering if any one can share any material for her to read through.

Thank you in advance.

Hello,

It's great that your daughter is so interested in the topic and wants to learn more! First of all, the project itself has a "make it your own" tab which suggests several variations on the project, including using different conductors (aluminum or brass tubes, for example) or using a different diameter of pipe. In addition, these resources may help her learn more about electricity and magnetism:

I would also suggest using the Science Buddies Project Ideas tab to look up other projects involving magnets/maglevs, which might spark some ideas about how to expand on the question (look in the background sections of these projects, which often contain information as well as links to other informative websites on the topic). One of the projects you might want to consult would be Levitating Magnets: Floating Isn't Just for Magicians. Here is the link:

In addition, the internet has many great resources which you might consult; a simple google search about "eddy currents explained simply" or magnetic levitation should yield abundant reading material. I did find a link to an Exploratorium page which explains essentially the same experiment in greater detail: https://www.exploratorium.edu/snacks/eddy-currents. There are also a number of other sources available explaining the concept.

I hope this helps! Please feel free to respond with any questions!

Sincerely,
Elena Lee
