Expert Answer:

Reason is as follows,

If the magnetic field associated with the current in a conductor were in the same direction as the change in magnetic field that created it, these two magnetic fields would combine to give a net magnetic field which would in turn induce a current with twice the magnitude. This process would continue creating infinite current from just moving a magnet: this would be a violation of the law of conservation of energy.
