Here is another try at clarifying some of the explanation above which is difficult to
concisely present without pictures.
Two single turn DC carrying coils placed near to each other, and on the same axis, are merely two bent around parallel wires which will attract or repel each other depending on whether their parallel currents are in the same, or opposite, directions. If two single
turn DC carrying coils are each formed into an equal sized square, and the two squares are placed near to each other on the same axis, it will be seen that there are, in this case, 4 sets of parallel wires shared between the two coils. Between the two squared coils there may be either attraction or repulsion, depending on whether their parallel currents are in the same direction or the opposing direction. Since merely flipping the face of one of the squares, 180 degrees, automatically reverses the
current spatially, the previous physical attraction or repulsion between the two squares will then also be reversed.
Since the working force between the two squared coils is obviously the effects of
close parallel currents rather than a mysterious force in the middle of each of the two coils, called a magnetic field, it is apparent that what we call a magnetic field is only the VECTOR RESULTANT of the distributed forces around the perimeters of, and between, the two coils.
Since physical magnets show the same physical reactions between them as DC carrying coils show, I assume a similar process is at work between magnets, but, instead, it relies on the net effect of many separate micro electric currents within the magnets instead of single locatable currents.
