Attention @ all:



There is no attraction in eddie currents in aluminum or copper. eddie currents create the exact pole that is facing it. The aluminum creates a eddie current charge right below the magnet and gravity keeps the mag on the bar. As I said in a previous post one pole is stronger than the other. When you put the weaker side down it  does not create enough eddie currents, and the stronger magnetic flux  will start to create eddie and the small mag  starts to tumble kicking it off the plate. To make the mag stop tumbling try using a magnet with a lager surface area. If you are worried about the magnet being to strong use a ceramic.

A test was done on 90 degree copper and the effect was apparent. I haven't yet seen a 90 degree Al test, perhaps you'd like to do one. The effect on copper is probably not a good guage as to whether gravity comes into play, due to simple magnetic attraction.  I'd like to see a 90 degree test on Al.

Does your above explaination (ie. gravity, etc) account for this?

..I take it that you're not implying that there is no acttractive/repulsive affect?

(for the record, I don't know - I'm trying to learn)

Were the idea is correct, the application is a slight delay. The currents are a tendency to the right angle of the motion.  Different materials different delays.  For the most part this is ignored until the higher frequencies get involved.  It can become a big problem then.
So far this is still an interesting observation. so some thing from the mylow thing did happen. Strange how such works.

magnets are not attracted to copper. when you make the angle steeper gravity no longer holds the mag on the bar and it starts to tumble

Sure about that?
