I am not sure this is the right forum, but thought I would try, and you can flock me if I am wrong =)
I have a real world problem. However, I don't recall ever having studied electromagnetism, thus I don't really have the necessary background to tackle this problem. I tried to speed up my learning, by learning the basics, "north and south" pole for example, of a magnet.
Here are two pictures of the toy.

the problem is, the "turbine" or rotary part of the engine doesn't work as expected. Disassembling it, carefully, I was able to get it to work, but it's still rough. It makes a lot of noise, NOT from the wheels, but from the part inside rubbing against the magnet.
The toy is from a 1983 Lego train set. So, yes, it is older. =)
I think, in theory, the part inside should almost free be suspended, and powerfully in the middle, but I can put it in and out without issue.
I suspect, and from what I have read, magnets can wear out?
But, they can also be recharged? How would a novice find the north or south pole?
Any tips or help in understanding this problem would be great!
