There is no attraction force in this universe. If you want to move something you have to push it....The refrigerator magnet is not sucked, pulled or attracted to the refrigerator. The area between the two objects is made less repulsive by a flow of particles setup by the magnet, between the two objects...You will find no Scientist that demonstrates attraction forces. Just offering you an old tried and true understanding of the Universe. William McCormick

For example, it is difficult to think of gravity as only a repulsive force. How do you account for objects of different densities, but the same mass being measured to have the same weight on Earth? Shouldn't the lower density object displace more "space", and thus have more mass? If the low density object is compressed, it's mass doesn't change (except for perhaps a minor component of air displacement, which would not be a problem in a vacuum chamber).Likewise, you will have difficulties explaining the N/S attraction of magnets, but the N/N and S/S repulsion of magnets through a distance. What is missing between the magnets? What causes a compass to work?What about covalent chemical bonds? Ionic chemical bonds? Van der Waals forces and H bonding?Anyway, if you wish, follow up with a new discussion under "New Theories". Add a link here if you wish.
I think that magnetoforming of aluminium is probably done with a rapidly changing magnetic field, not a static one. This induces eddy currents in the aluminium, turning it into an electromagnet, and it is these currents which are repelled by the coils inside, and push the aluminium away. This is very standard electromagnetism.The flow of magnetism you are talking about is normally called magnetic flux. It isn't a real thing, it is just a way of interpreting the equations of electromagnetism in terms of something which the human mind can get a handle on.Arguably positive and negative were labelled the wrong way it might make more sense for electrons to be positive, but that is the way the convention was set up, so we are stuck with it.Possibly some of the reason that WWII era welders were not marked +ve and -ve was that they were probably running AC not DC, in which case there isn't a +ve and -ve electrode, just live and neutral, or whatever you want to call that.
