Mags,

In the pendulum test, you could also place a conductive material that covers a larger area underneath the magnet that isn't part of the cicuit.  There should be a gap between the magnet and this additional conductive material.


Thanks,

Try this test with both a solid connection and without a solid connection.

I'm thinking about a cresent shaped conductive material that either surrounds half or most of the conductve magnet in a diametrical configuration.  This may allow us to design a brushless motor without an induced net emf.

Could this concept be similar or related to the notched objects observed in NASA's failed tether experiment.

Broli,

I'm not sure if you're still following this thread or not, but wouldn't a conductive material that partially or mostly surrounds the rim of the magnet and is electrically isolated qualify as the open circuit we have been looking for?  I don't see why not, and I would love to hear your thoughts on this.

Thanks,

Mags,

You may be partially right.  In your initial experiment, there is more conductive material underneath the magnet than there is above the magnet, and this could cause an unequal breaking force between the top and bottom edges of the magnet, similiar to this video showing how a magnet will find the center of its own way on a conductive path,  https://www.youtube.com/watch?v=d4KKeA3RI98

Please let me know what you think.

Thanks,

Well, like I said earlier, the foil floor is not the usual path for current to flow like a wire. There may be some push and pull for all I know. There may be possible upward push, levitation, etc.

But thinking about it more recently, the foil seems to be key.  lol, what might be interesting is if we have a panel with foil on top also. Would the mag move still? Or would that want to make the mag move in the opposite direction, negating the original effect? That may be simple to do also. Would be neat if the mag shot forward and out of the foil sandwich. The top plate could be very thin plastic to mount the foil, like a larger piece of bubble pack that products are sold in, as to not have too much weight on the mag keeping it from moving.

Ok. Gunna start working on the film test.  In your post showing the foil under but no electrical connection, Im not sure the foil would help being there or not. Might even slow things down due to lenz.
