Ok... Please someone answer this for me! So, I take apart a VCR and among the various motors and the various parts of these motors; there is a piece of one of them that does'nt quite fit. As far as it goes I do know the roughly basic, and not so basic components of a number of different electric motors... This is generally the one that is the "shiny cased" larger one, and that should fairly well let you know which of the number of motors I am speaking of(if you choose to take a VCR apart for my questions sake). So what it is about it that gets me is that first of all once taking it apart you will see that the disc shaped ferrero magnet has an outer case on one side (once apart) that is magnetic only on the exposed magnets side. The other side is "some" metal that appearantly is impermeable to magnets altogether, the side from a profile is only maybe 1/4 of an inch, leaving the remaining metal casing to be less than 1/32. One side will pick up a wrench and the other won't even pick a BB or a small spring up. So that is confusing enough, seeing as the only thing even closely explaining my problem would be " dielectrics" which in this case is simply not it; and you know why if you have understanding enough of stuff. A metal may be non- conductive and impermeable to magnetism, but there is no metal of any sort that bluntly kills magnetic attraction!
