Hi, Just curious, but is a North pole the same field as emanates from the Earth’s North pole, or the field that comes from a compass’ North pointing end? Thanks Adrian -----Original Message----- On Behalf Of David Meeker Sent: 12 June 2001 23:07 To: femm@yahoogroups.com Subject: [femm] Re: FEMM simulations errors ?? `The way to see this is to think of each magnet as being composed of 2` `point poles of strength Q. For a N pole, the force on the pole is` `B*Q, where B is the flux density created by the stator permanent` `magnets. For a S pole, the force is -B*Q. When you look at it this` `way, you can see that the vertical force should be zero, and there` `should be a net horizontal force to the right. One reference for this` `trick is M. Lindeburg's "Engineer in Training Review Manual, 6th ed.,"` `1982.` `Dave Meeker` `--` `http://members.aol.com/_ht_a/dcm3c` `Your use of Yahoo! Groups is subject to the Yahoo! Terms of Service.`
