Flux question

    "
    as the current
    increases with time, the magnetic flux through the circuit loop due to this current also
    increases with time.


    This increasing flux creates an induced emf in the circuit.

    The
    direction of the induced emf is such that it would cause an induced current in the loop
    (if the loop did not already carry a current), which would establish a magnetic field
    opposing the change in the original magnetic field.
    "
    i cant understand the last part
    what current the change in flux creates
    in what direction??
