Amount of force 1 magnet with x electric energy can create against an opposing magnet

    Amount of force 1 magnet with"x"electric energy can create against an opposing magnet

    is there a formula which can allow me to calculate the amount of force which can be created by two opposing magnetic fields with a certain amount of electrical current?

    does the size of the magnet have much to do with the maximum amount of force the field can create ?

    maybe some formula involving : SIZE of magnet, amount of current supplied, ANGLE (degrees) of opposing magnet with the same energy and DISTANCE between these two magnets?

    Use the Biot-Savart law to calculate the field from your wire geometry and then use dF = I dL x B to determine the force.
