bob14 Posted January 3, 2018 Report Share Posted January 3, 2018 Hi, I'm doing my extended essay in physics and I wanted some feedback on my topic. So the research question I'm thinking of is: To what extent does temperature impact the efficiency of a magnetic levitation device? This isn't the final wording (I need to rephrase "magnetic levitation device"), but the basic idea is that I would build a kind of quadcopter using rotating magnets and a copper plate. The eddy currents in the plate would cause it to heat up and I want to see if cooling the plate would have any effect on how much weight the quadcopter could hold. I got the idea from the video below. I think it has real world applications in things like maglev trains and such. Is this a good topic? I'm open to any suggestions anyone can offer.

kw0573 Posted January 3, 2018 Report Share Posted January 3, 2018 This is slightly unnecessary for an IA, but it's not bad. The topic should be phrased as investigating temperature-dependence of a certain phenomena/effect/law, not of a device. You should probably identify the specific type(s) of induced magnetic field from current. It's more important that you understand and explain the theory rather than build something from a YouTube video. Reply Link to post Share on other sites More sharing options...
bob14 Posted January 3, 2018 Author Report Share Posted January 3, 2018 Thank you for the advice! As for the temperature dependence of phenomena/effect/law vs of a device, the reason I wanted to do the levitation thing was because this is for an extended essay. I thought the physics EE had to be more than just an IA. Reply Link to post Share on other sites More sharing options...
kw0573 Posted January 3, 2018 Report Share Posted January 3, 2018 EE, yeah. You should still identify the theory in the topic instead of focus on a device in general. Building a device is unnecessary for EE too but it's not a bad idea. Reply Link to post Share on other sites More sharing options...
bob14 Posted January 3, 2018 Author Report Share Posted January 3, 2018 Okay, thank you. I'll rephrase to something like: "To what extent does temperature impact the efficiency of an induced magnetic field as described by Faraday's Law. Hopefully that focuses more on the theory. 1 Reply Link to post Share on other sites More sharing options...
