Hi Garry,

"When I try to push 2 magnets North to North together in free air they repel strongly. Yet in a piece of steel or Metglass etc they just cancel each other?"
That's because Metglass is a very good magnetic conductor. When placed between the two North poles the fields from each pole is deflected almost orthogonal through the good magnetic conductor and thus the poles are screened from each other. Air is a bad conductor of magnetism. Iron also deflects or screens the magnetic field but as iron is a much worse magnetic conductor as Metglass a thicker layer is needed for deflecting the same amount of magnetic flux.

Regards
Ole

 Hi Doug, Yes it's confusing for me also.

 It goes against logic a bit for me too.
 Please don't ask me why because I don't understand that deep.
 Though I'm certain it's true because it's the same for electric currents going opposite ways.
  
 
 With a big (Fish) magnet and a little (Fish) magnet they subtract from each other, in a magnetic path leaving only the difference in the direction of the big Fish.

 Hi GErry
 OK so magnetic forces can travel in two directions at once, sharing the same core?
 This goes against my twisted logic - as I have always thought like electrical flow the "big fish consumes the little fish" so if there is dominate strength and flow of electrical (and mmf) going one way, then that is the way it all goes and it just all gets consumed and swept along, like snowball consuming all in its path.
 The amount of backemf in the way will cause more resistance, OK, it will "slow" the movement, but the movement itself still all goes one way (I think so anyways but what do I know)
 

 "backemf" (or backmmf) to me is something inherent and locked tight with forward emf (or mmf) and just cannot be separated and is impossible or maybe it is possible to at least shove it sideways?
