Description of blocker movie: Apparatus description. Given that a piece of iron will prevent two repelling (like poles facing) magnets from pushing away could we insert a blocker so that those magnets could come together without being repelled then remove the metal blocker so that the magnets will repel and be pushed away from each other. This apparatus consists of two geared wheels that have two arc's extending above their plane and beyond the circles formed by the gears. Then one of those arc's has a repelling magnet that is matched by a stator magnet. The other gear has an arc that moves much faster than the smaller arc and repelling magnet. An arm in another plane above all of this is an arm that has the iron blocker. The iron blocker needs to arrive before the two repelling magnets and also be removed near dead center so that repelling will push the magnets away from each other. If I position the magnets at dead center and let go the apparatus will rotate about 360 degrees till the repel force stops it from moving. If you mechanically place a metal blocker between the repelling magnets then you will be able to get the repelling magnets closer. Then if you mechanically remove the metal blocker you will see the same almost 360 degree rotation. However what is the effort to insert the metal blocker and remove it? My gears came from the kind of lawn mower that pulls the front wheels. They are pretty crude but allow the necessary rotation. As the long arm with the metal blocker moves toward the two repelling magnets it will be drawn in because magnets attract metal. But it will also want to find a "sticky point" which is the closest magnet to metal place. So if either magnet is nearer to the metal the closer one will make a "sticky point". An then you will have to pay for moving away from it. So it is important that these be very centered to reduce the "sticky point". Norman
