direction of motion

[labview1958]

 

Which dimension short or long of the magnet is in the direction of motion.

[5614]

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".

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]

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.

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.
