hello....i was wondering ....consider a perfect circular wire..carrying a current...it produces a magnetic field..........now no current flows through it...bring a magnet near in along the axis ( or somehow, it doesn't matter ) ie, increase the flux in the loop by a constant rate...by EMI a current is induced....

now take a circular wire with a current ..it is similar to the wire having an induced current due to changing flux.....but in this case flux inside the loop doesn't change ie. time varying magnetic field wasn't produced......only a constant ( doesn't vary with time ) magnetic field is now produced .why ? why is EMI not reversible....where am i going wrong....plz answer.....................

love
