Hello, I realize this thread has been abandoned.  However I have some questions dealing with the original setup.

Does the original setup have the same reluctance with the washers closed verses when they are open?  This answer would save me a lot of time if anyone can answer that.  This was claimed to be the case in the beginning of the thread but I couldn't find where anyone verified this "fact". 

If you close the washers, does it take the same force to remove the magnet as when the washers are open - assuming you do not let the magnet touch the washers (in which case it should be harder to remove since the fanning washers will distribute the force over a larger area). 

Plain and simple question, does the first drawing in the beginning of this thread work the way it says it works?  If it does not, then why.  If it does then please someone must have verified this.  It will save me alot of time having to go back and retrace people's steps.

Thanks,
Charlie

So from the video, there is a great difference in reluctance from when the washers are closed verses when they are open.  The claim at the beginning of this thread is wrong and that moving the washers into the field when they are closed is much weaker from when they are allowed to open.
