Magnetic chuck weirdness
In article , Glenn Ashmore wrote:
I would surmise that if you use a bar magnet the flux lines have to flair out to get back around to the other pole. The chuck is a lot of narrow horse shoe magnets side by side so the flux just makes a short loop through the surface of what it is holding to get to the other pole. But that is just an opinion and you know what opinions are like... :-) Hmm... I like it. Now to figure out why the special v-blocks and parallels work... I suppose since they have narrow slices of magnetic material sandwiched between non-magnetic, then the flux has to continue up and do its looping over the top of the vee block. So I suppose if this is all correct that they would work the best when the iron/brass strips were lined up with the strips in the chuck. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Mike Graham | Metalworker, rustic, part-time zealot. | http://www.metalmangler.com| Caledon, Ontario, Canada |
