labview1958 Posted March 27, 2006 Share Posted March 27, 2006 Which dimension short or long of the magnet is in the direction of motion. Link to comment Share on other sites More sharing options...
5614 Posted March 27, 2006 Share Posted March 27, 2006 err, long. I don't see where the problem is. It is moving horizontally so the motion is along the horizontal axis, in this case labelled "long". Link to comment Share on other sites More sharing options...
labview1958 Posted March 28, 2006 Author Share Posted March 28, 2006 Let's say a magnet is moving with a velocity, v , over an aluminium "roadbed". Which configuration would give a stronger repulsion force: a. The shorter dimension in the direction o0f motion or b. The longer dimension in the direction of motion. C. both give a same force.

5614 Posted March 29, 2006 Share Posted March 29, 2006 I don't understand the question. If they both supply the same force and one is longer then it will be supplying that force for longer which would cause a greater acceleration... but like I said, I'm not really sure what you're asking.

labview1958 Posted March 30, 2006 Author Share Posted March 30, 2006 When a magnet moves over an aluminium sheet, it causes eddy current in it. This causes repulsion force between the magnet and it's image in the aluminium sheet. Which configuration causes the most force? This is all about MAGLEV.
