So I am trying to come up with a magnet parts lifting device that can be temporarily turned off
Their theory was, take two magnets (7x7x1.5mm in this case) place them between two iron plates with opposing poles and there should not be any field lines leaving the iron.
Take away one of the magnets and the work load closes the field line path, exerting a force
Well it did not work, with two opposing magnets present the force is only slightly less than with one.
Any ideas where I went wrong?
