    What is the repulsive force between the pair of like pole magnets? Is it flux?

    No. The units of flux are not the same as units of force.

    Officially,

    Weber (unit of magnetic flux) The weber is the magnetic flux which, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.[1]

    In SI base units, the dimensions of the weber are (kgm2)/(s2A). The weber is commonly expressed in terms of other derived units as the Tesla-square meter (Tm2), volt-seconds (Vs), or joules per ampere (J/A).

    1 Wb = 1 Vs = 1 Tm2 = 1 J/A = 108 Mx (maxwells).

    See this article for the method of calculating the force between magnets.

    Thanks Harold! let me go through it and come back if I have any questions... I was just thinking can the "Repulsive force" be used for one of my project... Just needed to confirm whether this is same as flux or not? So you mean to say if a moving conductor is placed in between this force, it is not going to produce current? Sorry, i have not yet looked into the details in the link (may be it have answer for the question)

    Just to clarify, I did not mean whether force and flux are same... I just wanted to know whether flux exists between the like poles of magnet, may be say both the magnets are at the vicinity of repulsion..
    To be more clearer : When opposite poles face each other they experience an "Attractive force" and flux exists between the two..
    Sorry if I am not clearer...
