The concentration of flux in low-reluctance materials forms strong temporary poles and causes mechanical forces that tend to move the materials towards regions of higher flux so it is always an attractive force(pull).


what are these mechanical forces.........

are they result of torque produced in the magnetic moments of the electrons for their alignment to

Are you referring here to "magnetostriction" within one core, or to the attraction of magnetic materials by magnets ?
