Subject: Re: Magnetizing Old Bar Magnets


A few years ago we obtained a magnetizer from ETP (Elector-Technic
Products), but the polarity was reversed. When I called them, they told
me that they set it up so that the "North" pole on the magnets they
created was the same as the "North" pole of the earth. Further, when I
explained the issue to them, they said that they had no intention of
changing. Of course, we corrected the wiring in the magnetizers. Has
anyone else had experience with these guys?
