So if I have an electromagnetic and I hold it next to the spinning metal disc as I increase the intensity of the magnetic field the metal disc should be harder to spin?
Define conductive? The eddy current breaks says non-ferromagnetic which means to me not having any magnetic properties like aluminum. I'm strictly interested in generating the magnetic resistance.

It sounds like you understand how it works, but are perhaps looking for the catch? I don't believe there is one... Note this works only as brake - however if you want the same phenomenon to work as a motor you are looking at a squirrel cage motor ([2]http://en.wikipedia.org/wiki/Induction_motor). _______________________________________________ geda-user mailing list [3]geda-user@moria.seul.org [4]http://www.seul.org/cgi-bin/mailman/listinfo/geda-user References 1. mailto:shinobi.j...@gmail.com 2. http://en.wikipedia.org/wiki/Induction_motor 3. mailto:geda-user@moria.seul.org 4. http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
